      "message": "fs: icache RCU free inodes\n\nRCU free the struct inode. This will allow:\n\n- Subsequent store-free path walking patch. The inode must be consulted for\n  permissions when walking, so an RCU inode reference is a must.\n- sb_inode_list_lock to be moved inside i_lock because sb list walkers who want\n  to take i_lock no longer need to take sb_inode_list_lock to walk the list in\n  the first place. This will simplify and optimize locking.\n- Could remove some nested trylock loops in dcache code\n- Could potentially simplify things a bit in VM land. Do not need to take the\n  page lock to follow page-\u003emapping.\n\nThe downsides of this is the performance cost of using RCU. In a simple\ncreat/unlink microbenchmark, performance drops by about 10% due to inability to\nreuse cache-hot slab objects. As iterations increase and RCU freeing starts\nkicking over, this increases to about 20%.\n\nIn cases where inode lifetimes are longer (ie. many inodes may be allocated\nduring the average life span of a single inode), a lot of this cache reuse is\nnot applicable, so the regression caused by this patch is smaller.\n\nThe cache-hot regression could largely be avoided by using SLAB_DESTROY_BY_RCU,\nhowever this adds some complexity to list walking and store-free path walking,\nso I prefer to implement this at a later date, if it is shown to be a win in\nreal situations. I haven\u0027t found a regression in any non-micro benchmark so I\ndoubt it will be a problem.\n\nSigned-off-by: Nick Piggin \u003cnpiggin@kernel.dk\u003e\n"

This means\nwe tie the quota code into the VFS.  Get rid of that and make the\nfilesystem responsible for the initialization.   For most metadata operations\nthis is a straight forward move into the methods, but for truncate and\nopen it\u0027s a bit more complicated.\n\nFor truncate we currently only call vfs_dq_init for the sys_truncate case\nbecause open already takes care of it for ftruncate and open(O_TRUNC) - the\nnew code causes an additional vfs_dq_init for those which is harmless.\n\nFor open the initialization is moved from do_filp_open into the open method,\nwhich means it happens slightly earlier now, and only for regular files.\nThe latter is fine because we don\u0027t need to initialize it for operations\non special files, and we already do it as part of the namespace operations\nfor directories.\n\nAdd a dquot_file_open helper that filesystems that support generic quotas\ncan use to fill in -\u003eopen.\n\nSigned-off-by: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Jan Kara \u003cjack@suse.cz\u003e\n"

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"

      "message": "fs: new inode i_state corruption fix\n\nThere was a report of a data corruption\nhttp://lkml.org/lkml/2008/11/14/121.  There is a script included to\nreproduce the problem.\n\nDuring testing, I encountered a number of strange things with ext3, so I\ntried ext2 to attempt to reduce complexity of the problem.  I found that\nfsstress would quickly hang in wait_on_inode, waiting for I_LOCK to be\ncleared, even though instrumentation showed that unlock_new_inode had\nalready been called for that inode.  This points to memory scribble, or\nsynchronisation problme.\n\ni_state of I_NEW inodes is not protected by inode_lock because other\nprocesses are not supposed to touch them until I_LOCK (and I_NEW) is\ncleared.  Adding WARN_ON(inode-\u003ei_state \u0026 I_NEW) to sites where we modify\ni_state revealed that generic_sync_sb_inodes is picking up new inodes from\nthe inode lists and passing them to __writeback_single_inode without\nwaiting for I_NEW.  Subsequently modifying i_state causes corruption.  In\nmy case it would look like this:\n\nCPU0                            CPU1\nunlock_new_inode()              __sync_single_inode()\n reg \u003c- inode-\u003ei_state\n reg -\u003e reg \u0026 ~(I_LOCK|I_NEW)   reg \u003c- inode-\u003ei_state\n reg -\u003e inode-\u003ei_state          reg -\u003e reg | I_SYNC\n                                reg -\u003e inode-\u003ei_state\n\nNon-atomic RMW on CPU1 overwrites CPU0 store and sets I_LOCK|I_NEW again.\n\nFix for this is rather than wait for I_NEW inodes, just skip over them:\ninodes concurrently being created are not subject to data integrity\noperations, and should not significantly contribute to dirty memory\neither.\n\nAfter this change, I\u0027m unable to reproduce any of the added warnings or\nhangs after ~1hour of running.  Previously, the new warnings would start\nimmediately and hang would happen in under 5 minutes.\n\nI\u0027m also testing on ext3 now, and so far no problems there either.  I\ndon\u0027t know whether this fixes the problem reported above, but it fixes a\nreal problem for me.\n\nCc: \"Jorge Boncompte [DTI2]\" \u003cjorge@dti2.net\u003e\nReported-by: Adrian Hunter \u003cext-adrian.hunter@nokia.com\u003e\nCc: Jan Kara \u003cjack@suse.cz\u003e\nCc: \u003cstable@kernel.org\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"
