      "message": "[PATCH] VFS: Permit filesystem to override root dentry on mount\n\nExtend the get_sb() filesystem operation to take an extra argument that\npermits the VFS to pass in the target vfsmount that defines the mountpoint.\n\nThe filesystem is then required to manually set the superblock and root dentry\npointers.  For most filesystems, this should be done with simple_set_mnt()\nwhich will set the superblock pointer and then set the root dentry to the\nsuperblock\u0027s s_root (as per the old default behaviour).\n\nThe get_sb() op now returns an integer as there\u0027s now no need to return the\nsuperblock pointer.\n\nThis patch permits a superblock to be implicitly shared amongst several mount\npoints, such as can be done with NFS to avoid potential inode aliasing.  In\nsuch a case, simple_set_mnt() would not be called, and instead the mnt_root\nand mnt_sb would be set directly.\n\nThe patch also makes the following changes:\n\n (*) the get_sb_*() convenience functions in the core kernel now take a vfsmount\n     pointer argument and return an integer, so most filesystems have to change\n     very little.\n\n (*) If one of the convenience function is not used, then get_sb() should\n     normally call simple_set_mnt() to instantiate the vfsmount. This will\n     always return 0, and so can be tail-called from get_sb().\n\n (*) generic_shutdown_super() now calls shrink_dcache_sb() to clean up the\n     dcache upon superblock destruction rather than shrink_dcache_anon().\n\n     This is required because the superblock may now have multiple trees that\n     aren\u0027t actually bound to s_root, but that still need to be cleaned up. The\n     currently called functions assume that the whole tree is rooted at s_root,\n     and that anonymous dentries are not the roots of trees which results in\n     dentries being left unculled.\n\n     However, with the way NFS superblock sharing are currently set to be\n     implemented, these assumptions are violated: the root of the filesystem is\n     simply a dummy dentry and inode (the real inode for \u0027/\u0027 may well be\n     inaccessible), and all the vfsmounts are rooted on anonymous[*] dentries\n     with child trees.\n\n     [*] Anonymous until discovered from another tree.\n\n (*) The documentation has been adjusted, including the additional bit of\n     changing ext2_* into foo_* in the documentation.\n\n[akpm@osdl.org: convert ipath_fs, do other stuff]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nAcked-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nCc: Nathan Scott \u003cnathans@sgi.com\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] Fix dcache race during umount\n\nThe race is that the shrink_dcache_memory shrinker could get called while a\nfilesystem is being unmounted, and could try to prune a dentry belonging to\nthat filesystem.\n\nIf it does, then it will call in to iput on the inode while the dentry is\nno longer able to be found by the umounting process.  If iput takes a\nwhile, generic_shutdown_super could get all the way though\nshrink_dcache_parent and shrink_dcache_anon and invalidate_inodes without\never waiting on this particular inode.\n\nEventually the superblock gets freed anyway and if the iput tried to touch\nit (which some filesystems certainly do), it will lose.  The promised\n\"Self-destruct in 5 seconds\" doesn\u0027t lead to a nice day.\n\nThe race is closed by holding s_umount while calling prune_one_dentry on\nsomeone else\u0027s dentry.  As a down_read_trylock is used,\nshrink_dcache_memory will no longer try to prune the dentry of a filesystem\nthat is being unmounted, and unmount will not be able to start until any\nsuch active prune_one_dentry completes.\n\nThis requires that prune_dcache *knows* which filesystem (if any) it is\ndoing the prune on behalf of so that it can be careful of other\nfilesystems.  shrink_dcache_memory isn\u0027t called it on behalf of any\nfilesystem, and so is careful of everything.\n\nshrink_dcache_anon is now passed a super_block rather than the s_anon list\nout of the superblock, so it can get the s_anon list itself, and can pass\nthe superblock down to prune_dcache.\n\nIf prune_dcache finds a dentry that it cannot free, it leaves it where it\nis (at the tail of the list) and exits, on the assumption that some other\nthread will be removing that dentry soon.  To try to make sure that some\nwork gets done, a limited number of dnetries which are untouchable are\nskipped over while choosing the dentry to work on.\n\nI believe this race was first found by Kirill Korotaev.\n\nCc: Jan Blunck \u003cjblunck@suse.de\u003e\nAcked-by: Kirill Korotaev \u003cdev@openvz.org\u003e\nCc: Olaf Hering \u003colh@suse.de\u003e\nAcked-by: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nSigned-off-by: Neil Brown \u003cneilb@suse.de\u003e\nSigned-off-by: Balbir Singh \u003cbalbir@in.ibm.com\u003e\nAcked-by: David Howells \u003cdhowells@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

Robin Holt notices that udev is one such culprit - it slows down a\n512-thread application on a 512 CPU system from 6 seconds to 22 minutes.\n\nSolve this by adding a flag in the dentry that tells inotify whether or not\nits parent inode has a watch on it.  Event queueing to parent will skip\ntaking locks if this flag is cleared.  Setting and clearing of this flag on\nall child dentries versus event delivery: this is no in terms of race\ncases, and that was shown to be equivalent to always performing the check.\n\nThe essential behaviour is that activity occuring _after_ a watch has been\nadded and _before_ it has been removed, will generate events.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nCc: Robert Love \u003crml@novell.com\u003e\nCc: John McCutchan \u003cttb@tentacle.dhs.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

Tested on both x86_64 and powerpc.\n\nThe way we do file struct accounting is not very suitable for batched\nfreeing.  For scalability reasons, file accounting was\nconstructor/destructor based.  This meant that nr_files was decremented\nonly when the object was removed from the slab cache.  This is susceptible\nto slab fragmentation.  With RCU based file structure, consequent batched\nfreeing and a test program like Serge\u0027s, we just speed this up and end up\nwith a very fragmented slab -\n\nllm22:~ # cat /proc/sys/fs/file-nr\n587730  0       758844\n\nAt the same time, I see only a 2000+ objects in filp cache.  The following\npatch I fixes this problem.\n\nThis patch changes the file counting by removing the filp_count_lock.\nInstead we use a separate percpu counter, nr_files, for now and all\naccesses to it are through get_nr_files() api.  In the sysctl handler for\nnr_files, we populate files_stat.nr_files before returning to user.\n\nCounting files as an when they are created and destroyed (as opposed to\ninside slab) allows us to correctly count open files with RCU.\n\nSigned-off-by: Dipankar Sarma \u003cdipankar@in.ibm.com\u003e\nCc: \"Paul E.

      "message": "[PATCH] fsnotify_name/inoderemove\n\nThe patch below unhooks fsnotify from vfs_unlink \u0026 vfs_rmdir.  It\nintroduces two new fsnotify calls, that are hooked in at the dcache\nlevel.  This not only more closely matches how the VFS layer works, it\nalso avoids the problem with locking and inode lifetimes.\n\nThe two functions are\n\n - fsnotify_nameremove -- called when a directory entry is going away.\n   It notifies the PARENT of the deletion.  This is called from\n   d_delete().\n\n - inoderemove -- called when the files inode itself is going away.  It\n   notifies the inode that is being deleted.  This is called from\n   dentry_iput().\n\nSigned-off-by: John McCutchan \u003cttb@tentacle.dhs.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
