It\u0027s not something\nthat people will often want to do, but it would be lame to demand a reboot\nwhen they\u0027re trying to determine which merge_across_nodes setting is best.\n\nHow can this happen? We only permit switching merge_across_nodes when\npages_shared is 0, and usually set run 2 to force that beforehand, which\nought to unmerge everything: yet oopses still occur when you then run 1.\n\nThree causes:\n\n1. The old stable tree (built according to the inverse\n merge_across_nodes) has not been fully torn down. A stable node\n lingers until get_ksm_page() notices that the page it references no\n longer references it: but the page is not necessarily freed as soon as\n expected, particularly when swapcache.\n\n Fix this with a pass through the old stable tree, applying\n get_ksm_page() to each of the remaining nodes (most found stale and\n removed immediately), with forced removal of any left over. Unless the\n page is still mapped: I\u0027ve not seen that case, it shouldn\u0027t occur, but\n better to WARN_ON_ONCE and EBUSY than BUG.\n\n2. __ksm_enter() has a nice little optimization, to insert the new mm\n just behind ksmd\u0027s cursor, so there\u0027s a full pass for it to stabilize\n (or be removed) before ksmd addresses it. Nice when ksmd is running,\n but not so nice when we\u0027re trying to unmerge all mms: we were missing\n those mms forked and inserted behind the unmerge cursor. Easily fixed\n by inserting at the end when KSM_RUN_UNMERGE.\n\n3. It is possible for a KSM page to be faulted back from swapcache\n into an mm, just after unmerge_and_remove_all_rmap_items() scanned past\n it. Fix this by copying on fault when KSM_RUN_UNMERGE: but that is\n private to ksm.c, so dissolve the distinction between\n ksm_might_need_to_copy() and ksm_does_need_to_copy(), doing it all in\n the one call into ksm.c.\n\nA long outstanding, unrelated bugfix sneaks in with that third fix:\nksm_does_need_to_copy() would copy from a !PageUptodate page (implying I/O\nerror when read in from swap) to a page which it then marks Uptodate. Fix\nthis case by not copying, letting do_swap_page() discover the error.\n\nSigned-off-by: Hugh Dickins \u003chughd@google.com\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Petr Holasek \u003cpholasek@redhat.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Izik Eidus \u003cizik.eidus@ravellosystems.com\u003e\nCc: Gerald Schaefer \u003cgerald.schaefer@de.ibm.com\u003e\nCc: KOSAKI Motohiro \u003ckosaki.motohiro@gmail.com\u003e\nAcked-by: Mel Gorman \u003cmgorman@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "22b751c3d0376e86a377e3a0aa2ddbbe9d2eefc1", "tree": "fe946d7d4350b2454d65f88377d264fbc93958ce", "parents": [ "e4715f01be697a3730c78f8ffffb595591d6a88c" ], "author": { "name": "Mel Gorman", "email": "mgorman@suse.de", "time": "Fri Feb 22 16:34:59 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Sat Feb 23 17:50:18 2013 -0800" }, "message": "mm: rename page struct field helpers\n\nThe function names page_xchg_last_nid(), page_last_nid() and\nreset_page_last_nid() were judged to be inconsistent so rename them to a\nstruct_field_op style pattern.

The main contention comes\nfrom swap_info_get(). This patch tries to fix the gap with adding a new\nper-partition lock.\n\nGlobal data like nr_swapfiles, total_swap_pages, least_priority and\nswap_list are still protected by swap_lock.\n\nnr_swap_pages is an atomic now, it can be changed without swap_lock. In\ntheory, it\u0027s possible get_swap_page() finds no swap pages but actually\nthere are free swap pages. But sounds not a big problem.\n\nAccessing partition specific data (like scan_swap_map and so on) is only\nprotected by swap_info_struct.lock.\n\nChanging swap_info_struct.flags need hold swap_lock and\nswap_info_struct.lock, because scan_scan_map() will check it. read the\nflags is ok with either the locks hold.\n\nIf both swap_lock and swap_info_struct.lock must be hold, we always hold\nthe former first to avoid deadlock.\n\nswap_entry_free() can change swap_list. To delete that code, we add a\nnew highest_priority_index. Whenever get_swap_page() is called, we\ncheck it. If it\u0027s valid, we use it.\n\nIt\u0027s a pity get_swap_page() still holds swap_lock(). But in practice,\nswap_lock() isn\u0027t heavily contended in my test with this patch (or I can\nsay there are other much more heavier bottlenecks like TLB flush). And\nBTW, looks get_swap_page() doesn\u0027t really need the lock. We never free\nswap_info[] and we check SWAP_WRITEOK flag.

The situation\n is pointed out first by Alan Stern. It is not a good approach to\n convert all GFP_KERNEL[1] in the path into GFP_NOIO because several\n subsystems may be involved(for example, PCI, USB and SCSI may be\n involved for usb mass stoarage device, network devices involved too in\n the iSCSI case)\n\n- during block device runtime suspend, because runtime resume need to\n wait for completion of concurrent runtime suspend.\n\n- during error handling of usb mass storage deivce, USB bus reset will\n be put on the device, so there shouldn\u0027t have any memory allocation with\n GFP_KERNEL during USB bus reset, otherwise the deadlock similar with\n above may be triggered. Unfortunately, any usb device may include one\n mass storage interface in theory, so it requires all usb interface\n drivers to handle the situation. In fact, most usb drivers don\u0027t know\n how to handle bus reset on the device and don\u0027t provide .pre_set() and\n .post_reset() callback at all, so USB core has to unbind and bind driver\n for these devices. So it is still not practical to resort to GFP_NOIO\n for solving the problem.\n\nAlso the introduced solution can be used by block subsystem or block\ndrivers too, for example, set the PF_MEMALLOC_NOIO flag before doing\nactual I/O transfer.\n\nIt is not a good idea to convert all these GFP_KERNEL in the affected\npath into GFP_NOIO because these functions doing that may be implemented\nas library and will be called in many other contexts.\n\nIn fact, memalloc_noio_flags() can convert some of current static\nGFP_NOIO allocation into GFP_KERNEL back in other non-affected contexts,\nat least almost all GFP_NOIO in USB subsystem can be converted into\nGFP_KERNEL after applying the approach and make allocation with GFP_NOIO\nonly happen in runtime resume/bus reset/block I/O transfer contexts\ngenerally.\n\n[1], several GFP_KERNEL allocation examples in runtime resume path\n\n- pci subsystem\nacpi_os_allocate\n\t\u003c-acpi_ut_allocate\n\t\t\u003c-ACPI_ALLOCATE_ZEROED\n\t\t\t\u003c-acpi_evaluate_object\n\t\t\t\t\u003c-__acpi_bus_set_power\n\t\t\t\t\t\u003c-acpi_bus_set_power\n\t\t\t\t\t\t\u003c-acpi_pci_set_power_state\n\t\t\t\t\t\t\t\u003c-platform_pci_set_power_state\n\t\t\t\t\t\t\t\t\u003c-pci_platform_power_transition\n\t\t\t\t\t\t\t\t\t\u003c-__pci_complete_power_transition\n\t\t\t\t\t\t\t\t\t\t\u003c-pci_set_power_state\n\t\t\t\t\t\t\t\t\t\t\t\u003c-pci_restore_standard_config\n\t\t\t\t\t\t\t\t\t\t\t\t\u003c-pci_pm_runtime_resume\n- usb subsystem\nusb_get_status\n\t\u003c-finish_port_resume\n\t\t\u003c-usb_port_resume\n\t\t\t\u003c-generic_resume\n\t\t\t\t\u003c-usb_resume_device\n\t\t\t\t\t\u003c-usb_resume_both\n\t\t\t\t\t\t\u003c-usb_runtime_resume\n\n- some individual usb drivers\nusblp, uvc, gspca, most of dvb-usb-v2 media drivers, cpia2, az6007, ....\n\nThat is just what I have found.

As a result, there is\nno way to decide when to split. We deal the larger pages in the\nfollowing way:\n\n1) For direct mapped pages, all the pages were freed when they were\n offlined. And since menmory offline is done section by section, all\n the memory ranges being removed are aligned to PAGE_SIZE. So only need\n to deal with unaligned pages when freeing vmemmap pages.\n\n2) For vmemmap pages being used to store page_struct, if part of the\n larger page is still in use, just fill the unused part with 0xFD.

In particular, rather than estimating how\n much memory we will need for page tables and then build them into that\n memory -- a calculation that has shown to be incredibly fragile -- we\n now build them (on 64 bits) with the aid of a \"pseudo-linear mode\" --\n a #PF handler which creates temporary page tables on demand.\n\n This has several advantages:\n\n 1. It makes it much easier to support things that need access to data\n very early (a followon patchset uses this to load microcode way\n early in the kernel startup).\n\n 2. It allows the kernel and all the kernel data objects to be invoked\n from above the 4 GB limit. This allows kdump to work on very large\n systems.\n\n 3. It greatly reduces the difference between Xen and native (Xen\u0027s\n equivalent of the #PF handler are the temporary page tables created\n by the domain builder), eliminating a bunch of fragile hooks.\n\n The patch series also gets us a bit closer to W^X.\n\n Additional work in this pull is the 64-bit get_user() work which you\n were also involved with, and a bunch of cleanups/speedups to\n __phys_addr()/__pa().\"\n\n* \u0027x86-mm-for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (105 commits)\n x86, mm: Move reserving low memory later in initialization\n x86, doc: Clarify the use of asm(\"%edx\") in uaccess.h\n x86, mm: Redesign get_user with a __builtin_choose_expr hack\n x86: Be consistent with data size in getuser.S\n x86, mm: Use a bitfield to mask nuisance get_user() warnings\n x86/kvm: Fix compile warning in kvm_register_steal_time()\n x86-32: Add support for 64bit get_user()\n x86-32, mm: Remove reference to alloc_remap()\n x86-32, mm: Remove reference to resume_map_numa_kva()\n x86-32, mm: Rip out x86_32 NUMA remapping code\n x86/numa: Use __pa_nodebug() instead\n x86: Don\u0027t panic if can not alloc buffer for swiotlb\n mm: Add alloc_bootmem_low_pages_nopanic()\n x86, 64bit, mm: hibernate use generic mapping_init\n x86, 64bit, mm: Mark data/bss/brk to nx\n x86: Merge early kernel reserve for 32bit and 64bit\n x86: Add Crash kernel low reservation\n x86, kdump: Remove crashkernel range find limit for 64bit\n memblock: Add memblock_mem_size()\n x86, boot: Not need to check setup_header version for setup_data\n ...\n" }, { "commit": "81ec44a6c69342fec1b1140c60a604027e429f69", "tree": "ee6bec8a94ef28e111bf766cf4b7a9366cb4f7c1", "parents": [ "48a732dfaa77a4dfec803aa8f248373998704f76", "e80cfc31d872b6b85b8966bce6ba80bee401a7dd" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:54:03 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:54:03 2013 -0800" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux\n\nPull s390 update from Martin Schwidefsky:\n \"The most prominent change in this patch set is the software dirty bit\n patch for s390.

This should provide stable page write support\nto most filesystems, while eliminating unnecessary waiting for devices\nthat don\u0027t require the feature.\n\nBefore this patchset, all filesystems would block, regardless of whether\nor not it was necessary. ext3 would wait, but still generate occasional\nchecksum errors.

First, it\nprovides creators (devices and filesystems) of a backing_dev_info a flag\nthat declares whether or not it is necessary to ensure that page\ncontents cannot change during writeout. It is no longer assumed that\nthis is true of all devices (which was never true anyway). Second, the\nflag is used to relaxed the wait_on_page_writeback calls so that wait\nonly occurs if the device needs it. Third, it fixes up the remaining\ndisk-backed filesystems to use this improved conditional-wait logic to\nprovide stable page writes on those filesystems.\n\nIt is hoped that (for people not using checksumming devices, anyway)\nthis patchset will give back unnecessary performance decreases since the\noriginal stable page write patchset went into 3.0. Sorry about not\nfixing it sooner.\n\nComplaints were registered by several people about the long write\nlatencies introduced by the original stable page write patchset.\nGenerally speaking, the kernel ought to allocate as little extra memory\nas possible to facilitate writeout, but for people who simply cannot\nwait, a second page stability strategy is (re)introduced: snapshotting\npage contents. The waiting behavior is still the default strategy; to\nenable page snapshotting, a superblock flag (MS_SNAP_STABLE) must be\nset. This flag is used to bandaid^Henable stable page writeback on\next3[1], and is not used anywhere else.\n\nGiven that there are already a few storage devices and network FSes that\nhave rolled their own page stability wait/page snapshot code, it would\nbe nice to move towards consolidating all of these. It seems possible\nthat iscsi and raid5 may wish to use the new stable page write support\nto enable zero-copy writeout.\n\nThank you to Jan Kara for helping fix a couple more filesystems.\n\nPer Andrew Morton\u0027s request, here are the result of using dbench to measure\nlatencies on ext2:\n\n3.8.0-rc3:\n Operation Count AvgLat MaxLat\n ----------------------------------------\n WriteX 109347 0.028 59.817\n ReadX 347180 0.004 3.391\n Flush 15514 29.828 287.283\n\n Throughput 57.429 MB/sec 4 clients 4 procs max_latency\u003d287.290 ms\n\n3.8.0-rc3 + patches:\n WriteX 105556 0.029 4.273\n ReadX 335004 0.005 4.112\n Flush 14982 30.540 298.634\n\n Throughput 55.4496 MB/sec 4 clients 4 procs max_latency\u003d298.650 ms\n\nAs you can see, for ext2 the maximum write latency decreases from ~60ms\non a laptop hard disk to ~4ms. I\u0027m not sure why the flush latencies\nincrease, though I suspect that being able to dirty pages faster gives\nthe flusher more work to do.\n\nOn ext4, the average write latency decreases as well as all the maximum\nlatencies:\n\n3.8.0-rc3:\n WriteX 85624 0.152 33.078\n ReadX 272090 0.010 61.210\n Flush 12129 36.219 168.260\n\n Throughput 44.8618 MB/sec 4 clients 4 procs max_latency\u003d168.276 ms\n\n3.8.0-rc3 + patches:\n WriteX 86082 0.141 30.928\n ReadX 273358 0.010 36.124\n Flush 12214 34.800 165.689\n\n Throughput 44.9941 MB/sec 4 clients 4 procs max_latency\u003d165.722 ms\n\nXFS seems to exhibit similar latency improvements as ext2:\n\n3.8.0-rc3:\n WriteX 125739 0.028 104.343\n ReadX 399070 0.005 4.115\n Flush 17851 25.004 131.390\n\n Throughput 66.0024 MB/sec 4 clients 4 procs max_latency\u003d131.406 ms\n\n3.8.0-rc3 + patches:\n WriteX 123529 0.028 6.299\n ReadX 392434 0.005 4.287\n Flush 17549 25.120 188.687\n\n Throughput 64.9113 MB/sec 4 clients 4 procs max_latency\u003d188.704 ms\n\n...and btrfs, just to round things out, also shows some latency\ndecreases:\n\n3.8.0-rc3:\n WriteX 67122 0.083 82.355\n ReadX 212719 0.005 2.828\n Flush 9547 47.561 147.418\n\n Throughput 35.3391 MB/sec 4 clients 4 procs max_latency\u003d147.433 ms\n\n3.8.0-rc3 + patches:\n WriteX 64898 0.101 71.631\n ReadX 206673 0.005 7.123\n Flush 9190 47.963 219.034\n\n Throughput 34.0795 MB/sec 4 clients 4 procs max_latency\u003d219.044 ms\n\nBefore this patchset, all filesystems would block, regardless of whether\nor not it was necessary. ext3 would wait, but still generate occasional\nchecksum errors. The network filesystems were left to do their own\nthing, so they\u0027d wait too.\n\nAfter this patchset, all the disk filesystems except ext3 and btrfs will\nwait only if the hardware requires it. ext3 (if necessary) snapshots\npages instead of blocking, and btrfs provides its own bdi so the mm will\nnever wait. Network filesystems haven\u0027t been touched, so either they\nprovide their own wait code, or they don\u0027t block at all. The blocking\nbehavior is back to what it was before 3.0 if you don\u0027t have a disk\nrequiring stable page writes.\n\nThis patchset has been tested on 3.8.0-rc3 on x64 with ext3, ext4, and\nxfs. I\u0027ve spot-checked 3.8.0-rc4 and seem to be getting the same\nresults as -rc3.\n\n[1] The alternative fixes to ext3 include fixing the locking order and\npage bit handling like we did for ext4 (but then why not just use\next4?), or setting PG_writeback so early that ext3 becomes extremely\nslow. I tried that, but the number of write()s I could initiate dropped\nby nearly an order of magnitude. That was a bit much even for the\nauthor of the stable page series! :)\n\nThis patch:\n\nCreates a per-backing-device flag that tracks whether or not pages must\nbe held immutable during writeout. Eventually it will be used to waive\nwait_for_page_writeback() if nothing requires stable pages.\n\nSigned-off-by: Darrick J.

The\nreason it\u0027s \"some\" cases is that as of gcc 4.4, the negative-sized array\nwill not create an error in some situations, like inline functions.\n\nThis patch replaces the negative-sized array code with the new\n__compiletime_error_fallback() macro which expands to the same thing\nunless the the error attribute is available, in which case it expands to\ndo{}while(0), resulting in exactly one compile-time error on all\nversions of gcc.\n\nNote that we are not changing the negative-sized array code for the\nunoptimized version of BUILD_BUG_ON, since it has the potential to catch\nproblems that would be disabled in later versions of gcc were\n__compiletime_error_fallback used. The reason is that that an\nunoptimized build can\u0027t always remove calls to an error-attributed\nfunction call (like we are using) that should effectively become dead\ncode if it were optimized. However, using a negative-sized array with a\nsimilar value will not result in an false-positive (error). The only\ncaveat being that it will also fail to catch valid conditions, which we\nshould be expecting in an unoptimized build anyway.\n\nSigned-off-by: Daniel Santos \u003cdaniel.santos@pobox.com\u003e\nCc: Andi Kleen \u003cak@linux.intel.com\u003e\nCc: Borislav Petkov \u003cbp@alien8.de\u003e\nCc: David Rientjes \u003crientjes@google.com\u003e\nCc: Joe Perches \u003cjoe@perches.com\u003e\nCc: Josh Triplett \u003cjosh@joshtriplett.org\u003e\nCc: Paul Gortmaker \u003cpaul.gortmaker@windriver.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a3ccc497cd17147713363a4bf975f1a269fadb6d", "tree": "6c5e14d9b9f8687edba0ee5a604277433d4db7d2", "parents": [ "1d6a0d19c85587581a364850b77f30446810a560" ], "author": { "name": "Daniel Santos", "email": "daniel.santos@pobox.com", "time": "Thu Feb 21 16:41:52 2013 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Feb 21 17:22:16 2013 -0800" }, "message": "bug.h: make BUILD_BUG_ON generate compile-time error\n\nNegative sized arrays wont create a compile-time error in some cases\nstarting with gcc 4.4 (e.g., inlined functions), but gcc 4.3 introduced\nthe error function attribute that will.\n\nThis patch modifies BUILD_BUG_ON to behave like BUILD_BUG already does,\nusing the error function attribute so that you don\u0027t have to build the\nentire kernel to discover that you have a problem, and then enjoy trying\nto track it down from a link-time error.\n\nAlso, we are only including asm/bug.h and then expecting that\nlinux/compiler.h will eventually be included to define __linktime_error\n(used in BUILD_BUG_ON).
