The problem is that this doesn\u0027t get accounted well and\npenalizes a random allocator with a big latency spike caused by work\ngenerated from elsewhere.\n\nI think the best idea would be to avoid this. By design if possible, or\nby deferring the hard work to an asynchronous context. If the latter,\nthen the fs would probably want to throttle creation of new work with\nqueue size of the deferred work, but let\u0027s not get into those details.\n\nAnyway, the other obvious thing we looked at is the iprune_mutex which is\ncausing the cascading blocking. We could turn this into an rwsem to\nimprove concurrency. It is unreasonable to totally ban all potentially\nslow or blocking operations in inode reclaim, so I think this is a cheap\nway to get a small improvement.\n\nThis doesn\u0027t solve the whole problem of course. The process doing inode\nreclaim will still take the latency hit, and concurrent processes may end\nup contending on filesystem locks. So fs developers should keep these\nproblems in mind.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Jan Kara \u003cjack@ucw.cz\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "88e9d34c727883d7d6f02cf1475b3ec98b8480c7", "tree": "475f544536d52739e0929e7727cab5124e855a06", "parents": [ "b7ed698cc9d556306a4088c238e2ea9311ea2cb3" ], "author": { "name": "James Morris", "email": "jmorris@namei.org", "time": "Tue Sep 22 16:43:43 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 23 07:39:29 2009 -0700" }, "message": "seq_file: constify seq_operations\n\nMake all seq_operations structs const, to help mitigate against\nrevectoring user-triggerable function pointers.\n\nThis is derived from the grsecurity patch, although generated from scratch\nbecause it\u0027s simpler than extracting the changes from there.\n\nSigned-off-by: James Morris \u003cjmorris@namei.org\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nAcked-by: Casey Schaufler \u003ccasey@schaufler-ca.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "1fd7317d02ec03c6fdf072317841287933d06d24", "tree": "b7ac4d511896dbb21c1b76a27f6c4d5b4cb6c7bb", "parents": [ "af91322ef3f29ae4114e736e2a72e28b4d619cf9" ], "author": { "name": "Nick Black", "email": "dank@qemfd.net", "time": "Tue Sep 22 16:43:33 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Sep 23 07:39:28 2009 -0700" }, "message": "Move magic numbers into magic.h\n\nMove various magic-number definitions into magic.h.\n\nSigned-off-by: Nick Black \u003cdank@qemfd.net\u003e\nAcked-by: Pekka Enberg \u003cpenberg@cs.helsinki.fi\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: \"David S.

This mapping will borrow\nfunctionality from the huge page shm code to create a file on the kernel\ninternal mount and use it to approximate an anonymous mapping. The\nMAP_HUGETLB flag is a modifier to MAP_ANONYMOUS and will not work without\nboth flags being preset.\n\nA new flag is necessary because there is no other way to hook into huge\npages without creating a file on a hugetlbfs mount which wouldn\u0027t be\nMAP_ANONYMOUS.\n\nTo userspace, this mapping will behave just like an anonymous mapping\nbecause the file is not accessible outside of the kernel.\n\nThis patchset is meant to simplify the programming model. Presently there\nis a large chunk of boiler platecode, contained in libhugetlbfs, required\nto create private, hugepage backed mappings. This patch set would allow\nuse of hugepages without linking to libhugetlbfs or having hugetblfs\nmounted.\n\nUnification of the VM code would provide these same benefits, but it has\nbeen resisted each time that it has been suggested for several reasons: it\nwould break PAGE_SIZE assumptions across the kernel, it makes page-table\nabstractions really expensive, and it does not provide any benefit on\narchitectures that do not support huge pages, incurring fast path\npenalties without providing any benefit on these architectures.\n\nThis patch:\n\nThere are two means of creating mappings backed by huge pages:\n\n 1. mmap() a file created on hugetlbfs\n 2. Use shm which creates a file on an internal mount which essentially\n maps it MAP_SHARED\n\nThe internal mount is only used for shared mappings but there is very\nlittle that stops it being used for private mappings. This patch extends\nhugetlbfs_file_setup() to deal with the creation of files that will be\nmapped MAP_PRIVATE on the internal hugetlbfs mount. This extended API is\nused in a subsequent patch to implement the MAP_HUGETLB mmap() flag.\n\nSigned-off-by: Eric Munson \u003cebmunson@us.ibm.com\u003e\nAcked-by: David Rientjes \u003crientjes@google.com\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: David Gibson \u003cdavid@gibson.dropbear.id.au\u003e\nCc: Lee Schermerhorn \u003clee.schermerhorn@hp.com\u003e\nCc: Nick Piggin \u003cnickpiggin@yahoo.com.au\u003e\nCc: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "3f96b79ad96263cc0ece7bb340cddf9b2ddfb1b3", "tree": "0da9828c16543164f1b055fd927ea3e222ca05e5", "parents": [ "cdf7b3418ad5a8783efe8f9124023d9b869fec0f" ], "author": { "name": "Hugh Dickins", "email": "hugh.dickins@tiscali.co.uk", "time": "Mon Sep 21 17:03:37 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:41 2009 -0700" }, "message": "tmpfs: depend on shmem\n\nCONFIG_SHMEM off gives you (ramfs masquerading as) tmpfs, even when\nCONFIG_TMPFS is off: that\u0027s a little anomalous, and I\u0027d intended to make\nmore sense of it by removing CONFIG_TMPFS altogether, always enabling its\ncode when CONFIG_SHMEM; but so many defconfigs have CONFIG_SHMEM on\nCONFIG_TMPFS off that we\u0027d better leave that as is.\n\nBut there is no point in asking for CONFIG_TMPFS if CONFIG_SHMEM is off:\nmake TMPFS depend on SHMEM, which also prevents TMPFS_POSIX_ACL\nshmem_acl.o being pointlessly built into the kernel when SHMEM is off.\n\nAnd a selfish change, to prevent the world from being rebuilt when I\nswitch between CONFIG_SHMEM on and off: the only CONFIG_SHMEM in the\nheader files is mm.h shmem_lock() - give that a shmem.c stub instead.\n\nSigned-off-by: Hugh Dickins \u003chugh.dickins@tiscali.co.uk\u003e\nAcked-by: Matt Mackall \u003cmpm@selenic.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "f3e8fccd06d27773186a0094371daf2d84c79469", "tree": "46e652e6ac3588a26c6d3e38ea10274eb3fc2ea8", "parents": [ "1c3aff1ceec2cc86810e2690e67873ff0c505862" ], "author": { "name": "Hugh Dickins", "email": "hugh.dickins@tiscali.co.uk", "time": "Mon Sep 21 17:03:25 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Tue Sep 22 07:17:40 2009 -0700" }, "message": "mm: add get_dump_page\n\nIn preparation for the next patch, add a simple get_dump_page(addr)\ninterface for the CONFIG_ELF_CORE dumpers to use, instead of calling\nget_user_pages() directly.

With pending\ncode like hw-breakpoints support the \u0027counter\u0027 name is less and\nless appropriate.\n\nAll in one, we\u0027ve decided to rename the subsystem to \u0027performance\nevents\u0027 and to propagate this rename through all fields, variables\nand API names. (in an ABI compatible fashion)\n\nThe word \u0027event\u0027 is also a bit shorter than \u0027counter\u0027 - which makes\nit slightly more convenient to write/handle as well.\n\nThanks goes to Stephane Eranian who first observed this misnomer and\nsuggested a rename.\n\nUser-space tooling and ABI compatibility is not affected - this patch\nshould be function-invariant. (Also, defconfigs were not touched to\nkeep the size down.)\n\nThis patch has been generated via the following script:\n\n FILES\u003d$(find * -type f | grep -vE \u0027oprofile|[^K]config\u0027)\n\n sed -i \\\n -e \u0027s/PERF_EVENT_/PERF_RECORD_/g\u0027 \\\n -e \u0027s/PERF_COUNTER/PERF_EVENT/g\u0027 \\\n -e \u0027s/perf_counter/perf_event/g\u0027 \\\n -e \u0027s/nb_counters/nb_events/g\u0027 \\\n -e \u0027s/swcounter/swevent/g\u0027 \\\n -e \u0027s/tpcounter_event/tp_event/g\u0027 \\\n $FILES\n\n for N in $(find . -name perf_counter.[ch]); do\n M\u003d$(echo $N | sed \u0027s/perf_counter/perf_event/g\u0027)\n mv $N $M\n done\n\n FILES\u003d$(find . -name perf_event.*)\n\n sed -i \\\n -e \u0027s/COUNTER_MASK/REG_MASK/g\u0027 \\\n -e \u0027s/COUNTER/EVENT/g\u0027 \\\n -e \u0027s/\\\u003cevent\\\u003e/event_id/g\u0027 \\\n -e \u0027s/counter/event/g\u0027 \\\n -e \u0027s/Counter/Event/g\u0027 \\\n $FILES\n\n... to keep it as correct as possible. This script can also be\nused by anyone who has pending perfcounters patches - it converts\na Linux kernel tree over to the new naming. We tried to time this\nchange to the point in time where the amount of pending patches\nis the smallest: the end of the merge window.\n\nNamespace clashes were fixed up in a preparatory patch - and some\nstylistic fallout will be fixed up in a subsequent patch.\n\n( NOTE: \u0027counters\u0027 are still the proper terminology when we deal\n with hardware registers - and these sed scripts are a bit\n over-eager in renaming them. I\u0027ve undone some of that, but\n in case there\u0027s something left where \u0027counter\u0027 would be\n better than \u0027event\u0027 we can undo that on an individual basis\n instead of touching an otherwise nicely automated patch. )\n\nSuggested-by: Stephane Eranian \u003ceranian@google.com\u003e\nAcked-by: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nAcked-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nReviewed-by: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nCc: Mike Galbraith \u003cefault@gmx.de\u003e\nCc: Arnaldo Carvalho de Melo \u003cacme@redhat.com\u003e\nCc: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nCc: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: David Howells \u003cdhowells@redhat.com\u003e\nCc: Kyle McMartin \u003ckyle@mcmartin.ca\u003e\nCc: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\nCc: \"David S.

The symptom is corrupted orphan lists and inodes\nwith the wrong i_size stored on disk. I was convinced the\ndata\u003dguarded code was just missing a call to ext3_mark_inode_dirty, but\ntracing showed the i_disksize I was sending to ext3_mark_inode_dirty\nwasn\u0027t actually making it to the drive.\n\next3_mark_inode_dirty can be called without locks held (atime updates\nand a few others), so the data\u003dguarded code uses locks while updating\nthe in-memory inode, and then calls ext3_mark_inode_dirty\nwithout any locks held.\n\nBut, ext3_mark_inode_dirty has no internal locking to make sure that\nonly one CPU is updating the buffer head at a time. Generally this\nworks out ok because everyone that changes the inode then calls\next3_mark_inode_dirty themselves. Even though it races, eventually\nsomeone updates the buffer heads and things move on.\n\nBut there is still a risk of the wrong values getting in, and the\ndata\u003dguarded code seems to hit the race very often.\n\nSince everyone that changes the inode also logs it, it should be\npossible to fix this with some memory barriers. I\u0027ll leave that as an\nexercise to the reader and lock the buffer head instead.\n\nIt it probably a good idea to have a different patch series for lockless\nbit flipping on the ext3 i_state field. ext3_do_update_inode \u0026\u003d clears\nEXT3_STATE_NEW without any locks held.\n\nSigned-off-by: Chris Mason \u003cchris.mason@oracle.com\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n" }, { "commit": "00171d3c7e3b738ba582c7a9b37408e796f49046", "tree": "4c43c59666d78ccb1522a99dd7966252d5878ccf", "parents": [ "3adae9da0b35d2ca908039f42a1e90395c335181" ], "author": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Tue Aug 11 19:06:10 2009 +0200" }, "committer": { "name": "Jan Kara", "email": "jack@suse.cz", "time": "Wed Sep 16 17:44:11 2009 +0200" }, "message": "ext3: Fix possible deadlock between ext3_truncate() and ext3_get_blocks()\n\nDuring truncate we are sometimes forced to start a new transaction as the\namount of blocks to be journaled is both quite large and hard to predict.
