That\u0027s doubly sad, since the common\ncase tends to be that there are no ACL\u0027s associated with the files in\nquestion.\n\next3 already caches the ACL data so that it doesn\u0027t have to look it up\nover and over again, but it does so by taking the inode-\u003ei_lock spinlock\non every lookup. Which is a noticeable overhead even if it\u0027s a private\nlock, especially on CPU\u0027s where the serialization is expensive (eg Intel\nNetburst aka \u0027P4\u0027).\n\nFor the special case of not actually having any ACL\u0027s, all that locking is\nunnecessary. Even if somebody else were to be changing the ACL\u0027s on\nanother CPU, we simply don\u0027t care - if we\u0027ve seen a NULL ACL, we might as\nwell use it.\n\nSo just load the ACL speculatively without any locking, and if it was\nNULL, just use it. If it\u0027s non-NULL (either because we had a cached\nentry, or because the cache hasn\u0027t been filled in at all), it means that\nwe\u0027ll need to get the lock and re-load it properly.\n\nThis is noticeable even on Nehalem, which does locking quite well (much\nbetter than P4).

However, in ext[234]_lookup(), this\n-ESTALE can be propagated to userspace if the filesystem is corrupted such\nthat a directory entry references a deleted inode. This leads to a\nmisleading error message - \"Stale NFS file handle\" - and confusion on the\npart of the admin.\n\nThe bug can be easily reproduced by creating a new filesystem, making a\nlink to an unused inode using debugfs, then mounting and attempting to ls\n-l said link.\n\nThis patch thus changes ext3_lookup to return -EIO if it receives -ESTALE\nfrom ext3_iget(), as ext3 does for other filesystem metadata corruption;\nand also invokes the appropriate ext*_error functions when this case is\ndetected.\n\nSigned-off-by: Bryan Donlan \u003cbdonlan@gmail.com\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "45f902178022439795a21e14f886b8ccb49a75d2", "tree": "addf5725b2cd80be4a140a70499cc07f86635a23", "parents": [ "ecca9af0a98fdacfcdc73979d08481d7b27ff986" ], "author": { "name": "Wei Yongjun", "email": "yjwei@cn.fujitsu.com", "time": "Thu Apr 02 16:57:14 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 02 19:04:52 2009 -0700" }, "message": "ext3: use unsigned instead of int for type of blocksize in fs/ext3/namei.c\n\nUse unsigned instead of int for the parameter which carries a blocksize.\n\n[akpm@linux-foundation.org: coding-style fixes]\nSigned-off-by: Wei Yongjun \u003cyjwei@cn.fujitsu.com\u003e\nCc: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "039fd8ce6258e01ec29f1637f9bf1868dd877c55", "tree": "dcc90b006655eecad1d0cd82850feef2398976fa", "parents": [ "b277c884f7856ce0791b1e72079023a86767981b" ], "author": { "name": "Cyrus Massoumi", "email": "cyrusm@gmx.net", "time": "Thu Apr 02 16:57:12 2009 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Apr 02 19:04:52 2009 -0700" }, "message": "ext3: remove the BKL in ext3/ioctl.c\n\nReformat ext3/ioctl.c to make it look more like ext4/ioctl.c and remove\nthe BKL around ext3_ioctl().\n\nSigned-off-by: Cyrus Massoumi \u003ccyrusm@gmx.net\u003e\nCc: \u003clinux-ext4@vger.kernel.org\u003e\nAcked-by: Jan Kara \u003cjack@ucw.cz\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "ce3b0f8d5c2203301fc87f3aaaed73e5819e2a48", "tree": "ab952affafe18e604f6aaf6b13315b9435588e60", "parents": [ "f1191b50ec11c8e2ca766d6d99eb5bb9d2c084a3" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Sun Mar 29 19:08:22 2009 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Mar 31 23:00:26 2009 -0400" }, "message": "New helper -

They are done in write_begin, which would always\nassume that the filesystem can be entered from reclaim. 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. Filesystems can now act on\nthis flag in their write_begin function. 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.

Current code could fall back to non\nreservation allocation to prevent early ENOSPC after examing all the block\ngroups with reservation on , but this code was bypassed if the reservation\nwindow is turned off already, which is true in this case.\n\nThis patch fixed two issues:\n1) We don\u0027t need to turn off block reservation if the goal block group has\n0 free blocks left and continue search for the rest of block groups.\n\nCurrent code the intention is to turn off the block reservation if the\ngoal allocation group has a few (some) free blocks left (not enough for\nmake the desired reservation window),to try to allocation in the goal\nblock group, to get better locality. But if the goal blocks have 0 free\nblocks, it should leave the block reservation on, and continues search for\nthe next block groups,rather than turn off block reservation completely.\n\n2) we don\u0027t need to check the window size if the block reservation is off.\n\nThe problem was originally found and fixed in ext4.\n\nSigned-off-by: Mingming Cao \u003ccmm@us.ibm.com\u003e\nCc: Theodore Ts\u0027o \u003ctytso@mit.edu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "972fbf779832e5ad15effa7712789aeff9224c37", "tree": "8fba1c79ad44ad871684a3e1b1b638a8625d9495", "parents": [ "885e353c7427db7b60692789741b34e605b0b69b" ], "author": { "name": "Josef Bacik", "email": "jbacik@redhat.com", "time": "Sat Oct 18 20:27:55 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Mon Oct 20 08:52:37 2008 -0700" }, "message": "ext3: don\u0027t try to resize if there are no reserved gdt blocks left\n\nWhen trying to resize a ext3 fs and you run out of reserved gdt blocks,\nyou get an error that doesn\u0027t actually tell you what went wrong, it just\nsays that the gdb it picked is not correct, which is the case since you\ndon\u0027t have any reserved gdt blocks left.
