All three roles are\nhardcoded into migration_thread() and determining which job is\nscheduled is slightly messy.\n\nThis patch kills migration_thread and replaces all three uses with\ncpu_stop. The three different roles of migration_thread() are\nsplitted into three separate cpu_stop callbacks -\nmigration_cpu_stop(), active_load_balance_cpu_stop() and\nsynchronize_sched_expedited_cpu_stop() - and each use case now simply\nasks cpu_stop to execute the callback as necessary.\n\nsynchronize_sched_expedited() was implemented with private\npreallocated resources and custom multi-cpu queueing and waiting\nlogic, both of which are provided by cpu_stop.\nsynchronize_sched_expedited_count is made atomic and all other shared\nresources along with the mutex are dropped.\n\nsynchronize_sched_expedited() also implemented a check to detect cases\nwhere not all the callback got executed on their assigned cpus and\nfall back to synchronize_sched(). If called with cpu hotplug blocked,\ncpu_stop already guarantees that and the condition cannot happen;\notherwise, stop_machine() would break. However, this patch preserves\nthe paranoid check using a cpumask to record on which cpus the stopper\nran so that it can serve as a bisection point if something actually\ngoes wrong theree.\n\nBecause the internal execution state is no longer visible,\nrcu_expedited_torture_stats() is removed.\n\nThis patch also renames cpu_stop threads to from \"stopper/%d\" to\n\"migration/%d\". The names of these threads ultimately don\u0027t matter\nand there\u0027s no reason to make unnecessary userland visible changes.\n\nWith this patch applied, stop_machine() and sched now share the same\nresources. stop_machine() is faster without wasting any resources and\nsched migration users are much cleaner.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nAcked-by: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nCc: Josh Triplett \u003cjosh@freedesktop.org\u003e\nCc: Paul E.

A module which never has its\nactual reference drop below 1 may return a reference count of 0 due to\nthis race.\n\nModule removal generally runs under stop_machine, which prevents this\nrace causing bugs due to removal of in-use modules. However there are\nother real bugs in module.c code and driver code (module_refcount is\nexported) where the callers do not run under stop_machine.\n\nFix this by maintaining running per-cpu counters for the number of\nmodule refcount increments and the number of refcount decrements. The\nincrements are tallied after the decrements, so any decrement seen will\nalways have its corresponding increment counted. The final refcount is\nthe difference of the total increments and decrements, preventing a\nlow-refcount from being returned.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Rusty Russell \u003crusty@rustcorp.com.au\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "749d229761ff0135cc4e16b8a28b41ae2f6b2c35", "tree": "25551c8cfb38319211f5ee59e78462a0f6fb85c4", "parents": [ "795d580baec0d5386b83a8b557df47c20810e86b", "3dc9fef67f6292692dba181a6d0fd0211bd0a607" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 05 13:42:54 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Apr 05 13:42:54 2010 -0700" }, "message": "Merge branch \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs\n\n* \u0027for-linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/ericvh/v9fs:\n 9p: saving negative to unsigned char\n 9p: return on mutex_lock_interruptible()\n 9p: Creating files with names too long should fail with ENAMETOOLONG.\n 9p: Make sure we are able to clunk the cached fid on umount\n 9p: drop nlink remove\n fs/9p: Clunk the fid resulting from partial walk of the name\n 9p: documentation update\n 9p: Fix setting of protocol flags in v9fs_session_info structure.\n" }, { "commit": "5f712b2b73a9fc87fcc52124cfe8adefaa0c92f5", "tree": "0e7ab3cedba6b50cdf603c433b79ceebf23972b0", "parents": [ "d522ffbfb9fccf6eca283cd2e8b03cf3d21fb616" ], "author": { "name": "Daniel Mack", "email": "daniel@caiaq.de", "time": "Mon Mar 22 10:11:15 2010 +0100" }, "committer": { "name": "Mark Brown", "email": "broonie@opensource.wolfsonmicro.com", "time": "Mon Apr 05 19:14:11 2010 +0100" }, "message": "ALSA: ASoC: move dma_data from snd_soc_dai to snd_soc_pcm_stream\n\nThis fixes a memory corruption when ASoC devices are used in\nfull-duplex mode.

It takes task_lock()\n which is not irq-safe, but try_to_wake_up() can be called from irq.\n\nKill them, and change select_fallback_rq() to use cpu_possible_mask, like\nwe currently do without CONFIG_CPUSETS.\n\nAlso, with or without this patch, with or without CONFIG_CPUSETS, the\ncallers of select_fallback_rq() can race with each other or with\nset_cpus_allowed() pathes.\n\nThe subsequent patches try to to fix these problems.\n\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nSigned-off-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nLKML-Reference: \u003c20100315091003.GA9123@redhat.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "c9494727cf293ae2ec66af57547a3e79c724fec2", "tree": "44ae197b64fa7530ee695a90ad31326dda06f1e1", "parents": [ "6427462bfa50f50dc6c088c07037264fcc73eca1", "42be79e37e264557f12860fa4cc84b4de3685954" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 02 20:02:55 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 02 20:03:08 2010 +0200" }, "message": "Merge branch \u0027linus\u0027 into sched/core\n\nMerge reason: update to latest upstream\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "50d11d190afa4e21284b735bb0a092036f298f0b", "tree": "098257e5933d1b1a5cbbc3470cef20a4cb856836", "parents": [ "42be79e37e264557f12860fa4cc84b4de3685954", "ab310b5edb8b601bcb02491ed6f7676da4fd1757" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 02 19:29:17 2010 +0200" }, "committer": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Fri Apr 02 19:29:17 2010 +0200" }, "message": "Merge branch \u0027perf/urgent\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing into perf/urgent\n" }, { "commit": "042be38e6106ed70b42d096ab4a1ed4187e510e6", "tree": "fb3599873f28cf36dbc76b6cd0a84f3e89e5e8cb", "parents": [ "b4a5e8a1deca7e61ebaffb37344766b0f0e9f327" ], "author": { "name": "Yinghai Lu", "email": "yinghai@kernel.org", "time": "Thu Apr 01 14:32:43 2010 -0700" }, "committer": { "name": "H.

Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros. Each\n slab.h inclusion directive was examined and added manually as\n necessary.\n\n6. percpu.h was updated not to include slab.h.\n\n7. Build test were done on the following configurations and failures\n were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my\n distributed build env didn\u0027t work with gcov compiles) and a few\n more options had to be turned off depending on archs to make things\n build (like ipr on powerpc/64 which failed due to missing writeq).\n\n * x86 and x86_64 UP and SMP allmodconfig and a custom test config.\n * powerpc and powerpc64 SMP allmodconfig\n * sparc and sparc64 SMP allmodconfig\n * ia64 SMP allmodconfig\n * s390 SMP allmodconfig\n * alpha SMP allmodconfig\n * um on x86_64 SMP allmodconfig\n\n8. percpu.h modifications were reverted so that it could be applied as\n a separate patch and serve as bisection point.\n\nGiven the fact that I had only a couple of failures from tests on step\n6, I\u0027m fairly confident about the coverage of this conversion patch.\nIf there is a breakage, it\u0027s likely to be something in one of the arch\nheaders which should be easily discoverable easily on most builds of\nthe specific arch.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nGuess-its-ok-by: Christoph Lameter \u003ccl@linux-foundation.org\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: Lee Schermerhorn \u003cLee.Schermerhorn@hp.com\u003e\n" }, { "commit": "6631424fd2efd75e7394b318ad2a8597327857a9", "tree": "09cc31036c9c53c5faec578ad68d443fd53e1b3d", "parents": [ "c45140a996b511bccdcbbdbea7e36f001826bdf2", "c0cd884af045338476b8e69a61fceb3f34ff22f1" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:41:18 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:41:18 2010 -0700" }, "message": "Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6\n\n* git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-2.6: (33 commits)\n r8169: offical fix for CVE-2009-4537 (overlength frame DMAs)\n ipv6: Don\u0027t drop cache route entry unless timer actually expired.\n tulip: Add missing parens.\n r8169: fix broken register writes\n pcnet_cs: add new id\n bonding: fix broken multicast with round-robin mode\n drivers/net: Fix continuation lines\n e1000: do not modify tx_queue_len on link speed change\n net: ipmr/ip6mr: prevent out-of-bounds vif_table access\n ixgbe: Do not run all Diagnostic offline tests when VFs are active\n igb: use correct bits to identify if managability is enabled\n benet: Fix compile warnnings in drivers/net/benet/be_ethtool.c\n net: Add MSG_WAITFORONE flag to recvmmsg\n e1000e: do not modify tx_queue_len on link speed change\n igbvf: do not modify tx_queue_len on link speed change\n ipv4: Restart rt_intern_hash after emergency rebuild (v2)\n ipv4: Cleanup struct net dereference in rt_intern_hash\n net: fix netlink address dumping in IPv4/IPv6\n tulip: Fix null dereference in uli526x_rx_packet()\n gianfar: fix undo of reserve()\n ...\n" }, { "commit": "de329820e920cd9cfbc2127cad26a37026260cce", "tree": "c392dbee75854e1f0b950f9d16dcf03214c63e80", "parents": [ "ad4ba059005f18ec9e274966c16d99fc5ce8b2cd" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:30:19 2010 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 29 14:30:19 2010 -0700" }, "message": "ext3: fix broken handling of EXT3_STATE_NEW\n\nIn commit 9df93939b735 (\"ext3: Use bitops to read/modify\nEXT3_I(inode)-\u003ei_state\") ext3 changed its internal \u0027i_state\u0027 variable to\nuse bitops for its state handling.

Which makes no\nsense at all, and screws up all the code that checks whether the inode\nwas newly allocated.\n\nIn particular, it made the xattr code unhappy, and caused various random\nbehavior, like apparently\n\n\thttps://bugzilla.redhat.com/show_bug.cgi?id\u003d577911\n\nSo fix the initialization, and rename the field to match ext4 so that we\ndon\u0027t have this happen again.\n\nCc: James Morris \u003cjmorris@namei.org\u003e\nCc: Stephen Smalley \u003csds@tycho.nsa.gov\u003e\nCc: Daniel J Walsh \u003cdwalsh@redhat.com\u003e\nCc: Eric Paris \u003ceparis@redhat.com\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "367d6acceaacff1adc44f121543effb9c060e575", "tree": "d1c75af960ad59a594088df843e3fa662b691415", "parents": [ "55a07517edbf15b83f323644edf346726eccd7e0" ], "author": { "name": "viresh kumar", "email": "viresh.kumar@st.com", "time": "Mon Mar 29 05:29:56 2010 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Mon Mar 29 17:33:33 2010 +0100" }, "message": "ARM: 6003/1: removing compilation warning from pl061.h\n\npl061.h is using u8 type. including \u003clinux/types.h\u003e in pl061.h to avoid\nwarning.\n\nSigned-off-by: Viresh Kumar \u003cviresh.kumar@st.com\u003e\nAcked-by: Baruch Siach \u003cbaruch@tkos.co.il\u003e\nSigned-off-by: Russell King \u003crmk+kernel@arm.linux.org.uk\u003e\n" }, { "commit": "c36207a4624f15020f2918324405c1c88a5d4cbc", "tree": "e70f0955f830e7d32ac196ebe2ce3a22a768e4bf", "parents": [ "325ffc3633f1c30ef89d98d619f7e1497366e77c" ], "author": { "name": "viresh kumar", "email": "viresh.kumar@st.com", "time": "Mon Mar 29 05:28:32 2010 +0100" }, "committer": { "name": "Russell King", "email": "rmk+kernel@arm.linux.org.uk", "time": "Mon Mar 29 17:33:31 2010 +0100" }, "message": "ARM: 5999/1: Including device.h and resource.h header files in linux/amba/bus.h\n\nlinux/amba/bus.h have dependencies on linux/device.h and linux/resource.h, but\nit doesn\u0027t include them.
