This results in a null\npointer access and leads to a kernel panic.\n\nWhy this happens: In __vmalloc_node_range() called from vmalloc(), newly\nallocated vm_struct is added to vmlist at __get_vm_area_node() and then,\nsome fields of vm_struct such as nr_pages and pages are set at\n__vmalloc_area_node(). In other words, it is added to vmlist before it is\nfully initialized. At the same time, when the /proc/vmallocinfo is read,\nit accesses the pages field of vm_struct according to the nr_pages field\nat show_numa_info(). Thus, a null pointer access happens.\n\nThe patch adds the newly allocated vm_struct to the vmlist *after* it is\nfully initialized.

Previously it was considered acceptable by\nVM people for a small number of pages to be written back from reclaim with\ntesting generally showing about 0.3% of pages reclaimed were written back\n(higher if memory was low). That writing back a small number of pages is\nok has been heavily disputed for quite some time and Dave Chinner\nexplained it well;\n\n\tIt doesn\u0027t have to be a very high number to be a problem. IO\n\tis orders of magnitude slower than the CPU time it takes to\n\tflush a page, so the cost of making a bad flush decision is\n\tvery high. And single page writeback from the LRU is almost\n\talways a bad flush decision.\n\nTo complicate matters, filesystems respond very differently to requests\nfrom reclaim according to Christoph Hellwig;\n\n\txfs tries to write it back if the requester is kswapd\n\text4 ignores the request if it\u0027s a delayed allocation\n\tbtrfs ignores the request\n\nAs a result, each filesystem has different performance characteristics\nwhen under memory pressure and there are many pages being dirtied. In\nsome cases, the request is ignored entirely so the VM cannot depend on the\nIO being dispatched.\n\nThe objective of this series is to reduce writing of filesystem-backed\npages from reclaim, play nicely with writeback that is already in progress\nand throttle reclaim appropriately when writeback pages are encountered.\nThe assumption is that the flushers will always write pages faster than if\nreclaim issues the IO.\n\nA secondary goal is to avoid the problem whereby direct reclaim splices\ntwo potentially deep call stacks together.\n\nThere is a potential new problem as reclaim has less control over how long\nbefore a page in a particularly zone or container is cleaned and direct\nreclaimers depend on kswapd or flusher threads to do the necessary work.\nHowever, as filesystems sometimes ignore direct reclaim requests already,\nit is not expected to be a serious issue.\n\nPatch 1 disables writeback of filesystem pages from direct reclaim\n\tentirely. Anonymous pages are still written.\n\nPatch 2 removes dead code in lumpy reclaim as it is no longer able\n\tto synchronously write pages. This hurts lumpy reclaim but\n\tthere is an expectation that compaction is used for hugepage\n\tallocations these days and lumpy reclaim\u0027s days are numbered.\n\nPatches 3-4 add warnings to XFS and ext4 if called from\n\tdirect reclaim. With patch 1, this \"never happens\" and is\n\tintended to catch regressions in this logic in the future.\n\nPatch 5 disables writeback of filesystem pages from kswapd unless\n\tthe priority is raised to the point where kswapd is considered\n\tto be in trouble.\n\nPatch 6 throttles reclaimers if too many dirty pages are being\n\tencountered and the zones or backing devices are congested.\n\nPatch 7 invalidates dirty pages found at the end of the LRU so they\n\tare reclaimed quickly after being written back rather than\n\twaiting for a reclaimer to find them\n\nI consider this series to be orthogonal to the writeback work but it is\nworth noting that the writeback work affects the viability of patch 8 in\nparticular.\n\nI tested this on ext4 and xfs using fs_mark, a simple writeback test based\non dd and a micro benchmark that does a streaming write to a large mapping\n(exercises use-once LRU logic) followed by streaming writes to a mix of\nanonymous and file-backed mappings. The command line for fs_mark when\nbotted with 512M looked something like\n\n./fs_mark -d /tmp/fsmark-2676 -D 100 -N 150 -n 150 -L 25 -t 1 -S0 -s 10485760\n\nThe number of files was adjusted depending on the amount of available\nmemory so that the files created was about 3xRAM. For multiple threads,\nthe -d switch is specified multiple times.\n\nThe test machine is x86-64 with an older generation of AMD processor with\n4 cores. The underlying storage was 4 disks configured as RAID-0 as this\nwas the best configuration of storage I had available. Swap is on a\nseparate disk. Dirty ratio was tuned to 40% instead of the default of\n20%.\n\nTesting was run with and without monitors to both verify that the patches\nwere operating as expected and that any performance gain was real and not\ndue to interference from monitors.\n\nHere is a summary of results based on testing XFS.\n\n512M1P-xfs Files/s mean 32.69 ( 0.00%) 34.44 ( 5.08%)\n512M1P-xfs Elapsed Time fsmark 51.41 48.29\n512M1P-xfs Elapsed Time simple-wb 114.09 108.61\n512M1P-xfs Elapsed Time mmap-strm 113.46 109.34\n512M1P-xfs Kswapd efficiency fsmark 62% 63%\n512M1P-xfs Kswapd efficiency simple-wb 56% 61%\n512M1P-xfs Kswapd efficiency mmap-strm 44% 42%\n512M-xfs Files/s mean 30.78 ( 0.00%) 35.94 (14.36%)\n512M-xfs Elapsed Time fsmark 56.08 48.90\n512M-xfs Elapsed Time simple-wb 112.22 98.13\n512M-xfs Elapsed Time mmap-strm 219.15 196.67\n512M-xfs Kswapd efficiency fsmark 54% 56%\n512M-xfs Kswapd efficiency simple-wb 54% 55%\n512M-xfs Kswapd efficiency mmap-strm 45% 44%\n512M-4X-xfs Files/s mean 30.31 ( 0.00%) 33.33 ( 9.06%)\n512M-4X-xfs Elapsed Time fsmark 63.26 55.88\n512M-4X-xfs Elapsed Time simple-wb 100.90 90.25\n512M-4X-xfs Elapsed Time mmap-strm 261.73 255.38\n512M-4X-xfs Kswapd efficiency fsmark 49% 50%\n512M-4X-xfs Kswapd efficiency simple-wb 54% 56%\n512M-4X-xfs Kswapd efficiency mmap-strm 37% 36%\n512M-16X-xfs Files/s mean 60.89 ( 0.00%) 65.22 ( 6.64%)\n512M-16X-xfs Elapsed Time fsmark 67.47 58.25\n512M-16X-xfs Elapsed Time simple-wb 103.22 90.89\n512M-16X-xfs Elapsed Time mmap-strm 237.09 198.82\n512M-16X-xfs Kswapd efficiency fsmark 45% 46%\n512M-16X-xfs Kswapd efficiency simple-wb 53% 55%\n512M-16X-xfs Kswapd efficiency mmap-strm 33% 33%\n\nUp until 512-4X, the FSmark improvements were statistically significant.\nFor the 4X and 16X tests the results were within standard deviations but\njust barely.

For\nexample, in the vast majority of cases, there were fewer pages scanned by\ndirect reclaim implying in many cases that stalls due to direct reclaim\nare reduced. KSwapd is scanning more due to skipping dirty pages which is\nunfortunate but the CPU usage is still acceptable\n\nIn an earlier set of tests, I used blktrace and in almost all cases\nthroughput throughout the entire test was higher. However, I ended up\ndiscarding those results as recording blktrace data was too heavy for my\nliking.\n\nOn a laptop, I plugged in a USB stick and ran a similar tests of tests\nusing it as backing storage.

On the postive side, firefox launched\nmarginally faster with the patches applied. Time to completion for many\ntests was faster but more importantly - the \"Avg wait\" time as measured by\niostat was far lower implying the system would be more responsive. It was\nalso the case that \"Avg wait ms\" on the root filesystem was lower. I\ntested it manually and while the system felt slightly more responsive\nwhile copying data to a USB stick, it was marginal enough that it could be\nmy imagination.\n\nThis patch: do not writeback filesystem pages in direct reclaim.\n\nWhen kswapd is failing to keep zones above the min watermark, a process\nwill enter direct reclaim in the same manner kswapd does. If a dirty page\nis encountered during the scan, this page is written to backing storage\nusing mapping-\u003ewritepage.\n\nThis causes two problems. First, it can result in very deep call stacks,\nparticularly if the target storage or filesystem are complex. Some\nfilesystems ignore write requests from direct reclaim as a result. The\nsecond is that a single-page flush is inefficient in terms of IO. While\nthere is an expectation that the elevator will merge requests, this does\nnot always happen. Quoting Christoph Hellwig;\n\n\tThe elevator has a relatively small window it can operate on,\n\tand can never fix up a bad large scale writeback pattern.\n\nThis patch prevents direct reclaim writing back filesystem pages by\nchecking if current is kswapd. Anonymous pages are still written to swap\nas there is not the equivalent of a flusher thread for anonymous pages.\nIf the dirty pages cannot be written back, they are placed back on the LRU\nlists. There is now a direct dependency on dirty page balancing to\nprevent too many pages in the system being dirtied which would prevent\nreclaim making forward progress.\n\nSigned-off-by: Mel Gorman \u003cmgorman@suse.de\u003e\nReviewed-by: Minchan Kim \u003cminchan.kim@gmail.com\u003e\nCc: Dave Chinner \u003cdavid@fromorbit.com\u003e\nCc: Christoph Hellwig \u003chch@infradead.org\u003e\nCc: Johannes Weiner \u003cjweiner@redhat.com\u003e\nCc: Wu Fengguang \u003cfengguang.wu@intel.com\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nCc: Rik van Riel \u003criel@redhat.com\u003e\nCc: Mel Gorman \u003cmgorman@suse.de\u003e\nCc: Alex Elder \u003caelder@sgi.com\u003e\nCc: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nCc: Chris Mason \u003cchris.mason@oracle.com\u003e\nCc: Dave Hansen \u003cdave@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "e10d59f2c3decaf22cc5d3de7040eba202bc2df3", "tree": "68a25b573ddd1701d6a50f22b26287eca8e5c1ea", "parents": [ "bc3e53f682d93df677dbd5006a404722b3adfe18" ], "author": { "name": "Christoph Lameter", "email": "cl@linux.com", "time": "Mon Oct 31 17:07:34 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 31 17:30:46 2011 -0700" }, "message": "mm: add comments to explain mm_struct fields\n\nAdd comments to explain the page statistics field in the mm_struct.\n\n[akpm@linux-foundation.org: add missing ;]\nSigned-off-by: Christoph Lameter \u003ccl@linux.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "bc3e53f682d93df677dbd5006a404722b3adfe18", "tree": "f386c29f13626e2b7d98d5a52525a78a9b59e447", "parents": [ "f11c0ca501af89fc07b0d9f17531ba3b68a4ef39" ], "author": { "name": "Christoph Lameter", "email": "cl@linux.com", "time": "Mon Oct 31 17:07:30 2011 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 31 17:30:46 2011 -0700" }, "message": "mm: distinguish between mlocked and pinned pages\n\nSome kernel components pin user space memory (infiniband and perf) (by\nincreasing the page count) and account that memory as \"mlocked\".\n\nThe difference between mlocking and pinning is:\n\nA. mlocked pages are marked with PG_mlocked and are exempt from\n swapping.

There is also a symmetrical ability to copy from the current\nprocess\u0027s address space into a destination process\u0027s address space.\n\n- Use of /proc/pid/mem has been considered, but there are issues with\n using it:\n - Does not allow for specifying iovecs for both src and dest, assuming\n preadv or pwritev was implemented either the area read from or\n written to would need to be contiguous.\n - Currently mem_read allows only processes who are currently\n ptrace\u0027ing the target and are still able to ptrace the target to read\n from the target. This check could possibly be moved to the open call,\n but its not clear exactly what race this restriction is stopping\n (reason appears to have been lost)\n - Having to send the fd of /proc/self/mem via SCM_RIGHTS on unix\n domain socket is a bit ugly from a userspace point of view,\n especially when you may have hundreds if not (eventually) thousands\n of processes that all need to do this with each other\n - Doesn\u0027t allow for some future use of the interface we would like to\n consider adding in the future (see below)\n - Interestingly reading from /proc/pid/mem currently actually\n involves two copies! (But this could be fixed pretty easily)\n\nAs mentioned previously use of vmsplice instead was considered, but has\nproblems. Since you need the reader and writer working co-operatively if\nthe pipe is not drained then you block. Which requires some wrapping to\ndo non blocking on the send side or polling on the receive. In all to all\ncommunication it requires ordering otherwise you can deadlock. And in the\nexample of many MPI tasks writing to one MPI task vmsplice serialises the\ncopying.\n\nThere are some cases of MPI collectives where even a single copy interface\ndoes not get us the performance gain we could. For example in an\nMPI_Reduce rather than copy the data from the source we would like to\ninstead use it directly in a mathops (say the reduce is doing a sum) as\nthis would save us doing a copy. We don\u0027t need to keep a copy of the data\nfrom the source. I haven\u0027t implemented this, but I think this interface\ncould in the future do all this through the use of the flags - eg could\nspecify the math operation and type and the kernel rather than just\ncopying the data would apply the specified operation between the source\nand destination and store it in the destination.\n\nAlthough we don\u0027t have a \"second user\" of the interface (though I\u0027ve had\nsome nibbles from people who may be interested in using it for intra\nprocess messaging which is not MPI). This interface is something which\nhardware vendors are already doing for their custom drivers to implement\nfast local communication. And so in addition to this being useful for\nOpenMPI it would mean the driver maintainers don\u0027t have to fix things up\nwhen the mm changes.\n\nThere was some discussion about how much faster a true zero copy would\ngo. Here\u0027s a link back to the email with some testing I did on that:\n\nhttp://marc.info/?l\u003dlinux-mm\u0026m\u003d130105930902915\u0026w\u003d2\n\nThere is a basic man page for the proposed interface here:\n\nhttp://ozlabs.org/~cyeoh/cma/process_vm_readv.txt\n\nThis has been implemented for x86 and powerpc, other architecture should\nmainly (I think) just need to add syscall numbers for the process_vm_readv\nand process_vm_writev. There are 32 bit compatibility versions for\n64-bit kernels.\n\nFor arch maintainers there are some simple tests to be able to quickly\nverify that the syscalls are working correctly here:\n\nhttp://ozlabs.org/~cyeoh/cma/cma-test-20110718.tgz\n\nSigned-off-by: Chris Yeoh \u003cyeohc@au1.ibm.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: \"H.

i_mutex lock use of generic _file_llseek hurts. Independent processes\naccessing the same file synchronize over a single lock, even though\nthey have no need for synchronization at all.\n\nUnder high utilization this can cause llseek to scale very poorly on larger\nsystems.\n\nThis patch does some rethinking of the llseek locking model:\n\nFirst the 64bit f_pos is not necessarily atomic without locks\non 32bit systems. This can already cause races with read() today.\nThis was discussed on linux-kernel in the past and deemed acceptable.\nThe patch does not change that.\n\nLet\u0027s look at the different seek variants:\n\nSEEK_SET: Doesn\u0027t really need any locking.\nIf there\u0027s a race one writer wins, the other loses.\n\nFor 32bit the non atomic update races against read()\nstay the same. Without a lock they can also happen\nagainst write() now. The read() race was deemed\nacceptable in past discussions, and I think if it\u0027s\nok for read it\u0027s ok for write too.\n\n\u003d\u003e Don\u0027t need a lock.\n\nSEEK_END: This behaves like SEEK_SET plus it reads\nthe maximum size too. Reading the maximum size would have the\n32bit atomic problem. But luckily we already have a way to read\nthe maximum size without locking (i_size_read), so we\ncan just use that instead.\n\nWithout i_mutex there is no synchronization with write() anymore,\nhowever since the write() update is atomic on 64bit it just behaves\nlike another racy SEEK_SET. On non atomic 32bit it\u0027s the same\nas SEEK_SET.\n\n\u003d\u003e Don\u0027t need a lock, but need to use i_size_read()\n\nSEEK_CUR: This has a read-modify-write race window\non the same file. One could argue that any application\ndoing unsynchronized seeks on the same file is already broken.\nBut for the sake of not adding a regression here I\u0027m\nusing the file-\u003ef_lock to synchronize this. Using this\nlock is much better than the inode mutex because it doesn\u0027t\nsynchronize between processes.\n\n\u003d\u003e So still need a lock, but can use a f_lock.\n\nThis patch implements this new scheme in generic_file_llseek.\nI dropped generic_file_llseek_unlocked and changed all callers.\n\nSigned-off-by: Andi Kleen \u003cak@linux.intel.com\u003e\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\n" }, { "commit": "8522ca5818652c4da6808c66a307abce75462212", "tree": "dd127ea11faf379c3b4610eb9f15feee79cb802f", "parents": [ "8fd90c8d1dacb5ff0f372217c97f57a9e61559cd" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Sun Oct 23 23:13:31 2011 +0530" }, "committer": { "name": "root", "email": "root@serles.lst.de", "time": "Fri Oct 28 14:58:54 2011 +0200" }, "message": "vfs: add hex format for MAY_* flag values\n\nWe are going to add more flags and having them in hex format\nmake it simpler\n\nAcked-by: J.
