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": "e213e26ab3988c516c06eba4dcd030ac052f6dc9", "tree": "6e26fbdbb842b387697d73daf6e70cf718269a77", "parents": [ "c812a51d11bbe983f4c24e32b59b265705ddd3c2", "efd8f0e6f6c1faa041f228d7113bd3a9db802d49" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 05 13:20:53 2010 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Fri Mar 05 13:20:53 2010 -0800" }, "message": "Merge branch \u0027for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6\n\n* \u0027for_linus\u0027 of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs-2.6: (33 commits)\n quota: stop using QUOTA_OK / NO_QUOTA\n dquot: cleanup dquot initialize routine\n dquot: move dquot initialization responsibility into the filesystem\n dquot: cleanup dquot drop routine\n dquot: move dquot drop responsibility into the filesystem\n dquot: cleanup dquot transfer routine\n dquot: move dquot transfer responsibility into the filesystem\n dquot: cleanup inode allocation / freeing routines\n dquot: cleanup space allocation / freeing routines\n ext3: add writepage sanity checks\n ext3: Truncate allocated blocks if direct IO write fails to update i_size\n quota: Properly invalidate caches even for filesystems with blocksize \u003c pagesize\n quota: generalize quota transfer interface\n quota: sb_quota state flags cleanup\n jbd: Delay discarding buffers in journal_unmap_buffer\n ext3: quota_write cross block boundary behaviour\n quota: drop permission checks from xfs_fs_set_xstate/xfs_fs_set_xquota\n quota: split out compat_sys_quotactl support from quota.c\n quota: split out netlink notification support from quota.c\n quota: remove invalid optimization from quota_sync_all\n ...\n\nFixed trivial conflicts in fs/namei.c and fs/ufs/inode.c\n" }, { "commit": "a9185b41a4f84971b930c519f0c63bd450c4810d", "tree": "268cf4e206cca12fb9e1dd68984e7c190e465b46", "parents": [ "26821ed40b4230259e770c9911180f38fcaa6f59" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Fri Mar 05 09:21:37 2010 +0100" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Fri Mar 05 13:25:52 2010 -0500" }, "message": "pass writeback_control to -\u003ewrite_inode\n\nThis gives the filesystem more information about the writeback that\nis happening.

Also some explicit calls to\nlock_kernel() have been converted to reiserfs_write_lock() helpers.\n\nThe second axis is to find the important blocking sites (schedule...(),\nwait_on_buffer(), sync_dirty_buffer(), etc...) and then apply an explicit\nrelease of the write lock on these locations before blocking. Then we can\nsafely wait for those who can give us resources or those who need some.\nTypically this is a fight between the current writer, the reiserfs workqueue\n(aka the async commiter) and the pdflush threads.\n\nThe third axis is a consequence of the second. The write lock is usually\non top of a lock dependency chain which can include the journal lock, the\nflush lock or the commit lock. So it\u0027s dangerous to release and trying to\nreacquire the write lock while we still hold other locks.\n\nThis is fine with the bkl:\n\n T1 T2\n\nlock_kernel()\n mutex_lock(A)\n unlock_kernel()\n // do something\n lock_kernel()\n mutex_lock(A) -\u003e already locked by T1\n schedule() (and then unlock_kernel())\n lock_kernel()\n mutex_unlock(A)\n ....\n\nThis is not fine with a mutex:\n\n T1 T2\n\nmutex_lock(write)\n mutex_lock(A)\n mutex_unlock(write)\n // do something\n mutex_lock(write)\n mutex_lock(A) -\u003e already locked by T1\n schedule()\n\n mutex_lock(write) -\u003e already locked by T2\n deadlock\n\nThe solution in this patch is to provide a helper which releases the write\nlock and sleep a bit if we can\u0027t lock a mutex that depend on it. It\u0027s another\nsimulation of the bkl behaviour.\n\nThe last axis is to locate the fs callbacks that are called with the bkl held,\naccording to Documentation/filesystem/Locking.\n\nThose are:\n\n- reiserfs_remount\n- reiserfs_fill_super\n- reiserfs_put_super\n\nReiserfs didn\u0027t need to explicitly lock because of the context of these callbacks.\nBut now we must take care of that with the new locking.\n\nAfter this patch, reiserfs suffers from a slight performance regression (for now).\nOn UP, a high volume write with dd reports an average of 27 MB/s instead\nof 30 MB/s without the patch applied.\n\nSigned-off-by: Frederic Weisbecker \u003cfweisbec@gmail.com\u003e\nReviewed-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Jeff Mahoney \u003cjeffm@suse.com\u003e\nCc: Peter Zijlstra \u003ca.p.zijlstra@chello.nl\u003e\nCc: Bron Gondwana \u003cbrong@fastmail.fm\u003e\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Alexander Viro \u003cviro@zeniv.linux.org.uk\u003e\nLKML-Reference: \u003c1239070789-13354-1-git-send-email-fweisbec@gmail.com\u003e\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\n" }, { "commit": "281eede0328c84a8f20e0e85b807d5b51c3de4f2", "tree": "9eb0184c7066f27593f2fd75db1593bf688c330f", "parents": [ "7a77b15d9294749809de918e24bebc39e0fbc9ab" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Mon Jun 08 21:07:04 2009 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Wed Jun 24 08:17:06 2009 -0400" }, "message": "switch reiserfs to inode-\u003ei_acl\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "e1c502482853f84606928f5a2f2eb6da1993cda1", "tree": "ca296007164906342a195bdf3a5305277e6af5da", "parents": [ "019abbc87025a030fd25008612afd4eff8a375f7", "ee93961be1faddf9e9a638bc519145c20f0cfeba" ], "author": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 30 12:29:21 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 30 12:33:01 2009 -0700" }, "message": "Merge branch \u0027reiserfs-updates\u0027 from Jeff Mahoney\n\n* reiserfs-updates: (35 commits)\n reiserfs: rename [cn]_* variables\n reiserfs: rename p_._ variables\n reiserfs: rename p_s_tb to tb\n reiserfs: rename p_s_inode to inode\n reiserfs: rename p_s_bh to bh\n reiserfs: rename p_s_sb to sb\n reiserfs: strip trailing whitespace\n reiserfs: cleanup path functions\n reiserfs: factor out buffer_info initialization\n reiserfs: add atomic addition of selinux attributes during inode creation\n reiserfs: use generic readdir for operations across all xattrs\n reiserfs: journaled xattrs\n reiserfs: use generic xattr handlers\n reiserfs: remove i_has_xattr_dir\n reiserfs: make per-inode xattr locking more fine grained\n reiserfs: eliminate per-super xattr lock\n reiserfs: simplify xattr internal file lookups/opens\n reiserfs: Clean up xattrs when REISERFS_FS_XATTR is unset\n reiserfs: remove IS_PRIVATE helpers\n reiserfs: remove link detection code\n ...\n\nFixed up conflicts manually due to:\n - quota name cleanups vs variable naming changes:\n\tfs/reiserfs/inode.c\n\tfs/reiserfs/namei.c\n\tfs/reiserfs/stree.c\n fs/reiserfs/xattr.c\n - exported include header cleanups\n\tinclude/linux/reiserfs_fs.h\n" }, { "commit": "995c762ea486b48c9777522071fbf132dea96807", "tree": "d6d82ca71ca67a98687762b83ce2858eb8dc624f", "parents": [ "ad31a4fc0386e8590c51ca4b8f1ae1d8b8b2ac5e" ], "author": { "name": "Jeff Mahoney", "email": "jeffm@suse.com", "time": "Mon Mar 30 14:02:47 2009 -0400" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Mar 30 12:16:39 2009 -0700" }, "message": "reiserfs: rename p_s_inode to inode\n\nThis patch is a simple s/p_s_inode/inode/g to the reiserfs code.

This bug could\ncause filesystem deadlocks.\n\nThe funny thing with having a gfp_t mask there is that it doesn\u0027t really\nallow the caller to arbitrarily tinker with the context in which it can be\ncalled. It couldn\u0027t ever be GFP_ATOMIC, for example, because it needs to\ntake the page lock. The only thing any callers care about is __GFP_FS\nanyway, so turn that into a single flag.\n\nAdd a new flag for write_begin, AOP_FLAG_NOFS.

Change __grab_cache_page to\naccept a nofs argument as well, to honour that flag (while we\u0027re there,\nchange the name to grab_cache_page_write_begin which is more instructive\nand does away with random leading underscores).\n\nThis is really a more flexible way to go in the end anyway -- if a\nfilesystem happens to want any extra allocations aside from the pagecache\nones in ints write_begin function, it may now use GFP_KERNEL (rather than\nGFP_NOFS) for common case allocations (eg. ocfs2_alloc_write_ctxt, for a\nrandom example).\n\n[kosaki.motohiro@jp.fujitsu.com: fix ubifs]\n[kosaki.motohiro@jp.fujitsu.com: fix fuse]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nReviewed-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nCc: \u003cstable@kernel.org\u003e\t\t[2.6.28.x]\nSigned-off-by: KOSAKI Motohiro \u003ckosaki.motohiro@jp.fujitsu.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\n[ Cleaned up the calling convention: just pass in the AOP flags\n untouched to the grab_cache_page_write_begin() function.

After packing the\npage got cleared with clear_page_dirty. It did not take into account that\nthe page may be mmaped into other process\u0027s address space. Recent\nreplacement for clear_page_dirty cancel_dirty_page found the confusion with\nsanity check that page has to be not mapped.\n\nThe patch fixes the confusion by making reiserfs avoid tail packing if an\ninode was ever mmapped. reiserfs_mmap and reiserfs_file_release are\nserialized with mutex in reiserfs specific inode. reiserfs_mmap locks the\nmutex and sets a bit in reiserfs specific inode flags.\nreiserfs_file_release checks the bit having the mutex locked.
