That\u0027s doubly sad, since the common\ncase tends to be that there are no ACL\u0027s associated with the files in\nquestion.\n\next4 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\n(This commit was ported from a patch originally authored by Linus for\next3.)\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "4159175058987cb68aefd0e9eec2598b795363b4", "tree": "452a3ef5f8f2ae4c79095519078383fe766d69ab", "parents": [ "de9a55b841132f7ae097f6e31ccebad2d5030cf5" ], "author": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Jun 15 03:41:23 2009 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Mon Jun 15 03:41:23 2009 -0400" }, "message": "ext4: Don\u0027t update ctime for non-extent-mapped inodes\n\nThe VFS handles updating ctime, so we don\u0027t need to update the inode\u0027s\nctime in ext4_splace_branch() to update the direct or indirect blocks.\nThis was harmless when we did this in ext3, but in ext4, thanks to\ndelayed allocation, updating the ctime in ext4_splice_branch() can\ncause the ctime to mysteriously jump when the blocks are finally\nallocated.\n\nThanks to Björn Steinbrink for pointing out this problem on the git\nmailing list.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "62e086be5d2abef8cad854bc5707329ad345f2ec", "tree": "1f3ea5daf9325a338585e1368edf78a1d04747df", "parents": [ "43ce1d23b43330634507a049b55c36e91d27282e" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Sun Jun 14 17:59:34 2009 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sun Jun 14 17:59:34 2009 -0400" }, "message": "ext4: Move __ext4_journalled_writepage() to avoid forward declaration\n\nIn addition, fix two unused variable warnings.\n\nSigned-off-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "43ce1d23b43330634507a049b55c36e91d27282e", "tree": "d7532d7c0bea60b7bfe29dad51b4b92122acdd5a", "parents": [ "c364b22c9580a885e0f8c0d0f9710d67dc448958" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Sun Jun 14 17:58:45 2009 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sun Jun 14 17:58:45 2009 -0400" }, "message": "ext4: Fix mmap/truncate race when blocksize \u003c pagesize \u0026\u0026 !nodellaoc\n\nThis patch fixes the mmap/truncate race that was fixed for delayed\nallocation by merging ext4_{journalled,normal,da}_writepage() into\next4_writepage().\n\nSigned-off-by: Aneesh Kumar K.V \u003caneesh.kumar@linux.vnet.ibm.com\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n" }, { "commit": "c364b22c9580a885e0f8c0d0f9710d67dc448958", "tree": "6a714e767afb7d08a648f8e23e4acca414896699", "parents": [ "b767e78a179e5ab30fdbff1686d074ac270471eb" ], "author": { "name": "Aneesh Kumar K.V", "email": "aneesh.kumar@linux.vnet.ibm.com", "time": "Sun Jun 14 17:57:10 2009 -0400" }, "committer": { "name": "Theodore Ts\u0027o", "email": "tytso@mit.edu", "time": "Sun Jun 14 17:57:10 2009 -0400" }, "message": "ext4: Fix mmap/truncate race when blocksize \u003c pagesize \u0026\u0026 delayed allocation\n\nIt is possible to see buffer_heads which are not mapped in the\nwritepage callback in the following scneario (where the fs blocksize\nis 1k and the page size is 4k):\n\n1) truncate(f, 1024)\n2) mmap(f, 0, 4096)\n3) a[0] \u003d \u0027a\u0027\n4) truncate(f, 4096)\n5) writepage(...)\n\nNow if we get a writepage callback immediately after (4) and before an\nattempt to write at any other offset via mmap address (which implies we\nare yet to get a pagefault and do a get_block) what we would have is the\npage which is dirty have first block allocated and the other three\nbuffer_heads unmapped.\n\nIn the above case the writepage should go ahead and try to write the\nfirst blocks and clear the page_dirty flag.

All other callers of lock_super()\neither hold s_umount (and we have it exclusive) or hold an active\nreference to superblock in question, which prevents the call of\ngeneric_shutdown_super() while the reference is held. So we can\nreplace lock_super(s) with get_fs_excl() in generic_shutdown_super()\n(and corresponding change for unlock_super(), of course).\n\nSince ext4 expects s_lock held for its put_super, take lock_super()\ninto it. The rest of filesystems do not care at all.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "8c85e125124a473d6f3e9bb187b0b84207f81d91", "tree": "d883424a156c00c55193e46567efdffddb6ef6b9", "parents": [ "517bfae28353e996160518add4d00033d3886e61" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Tue Apr 28 18:00:26 2009 +0200" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu Jun 11 21:36:06 2009 -0400" }, "message": "remove -\u003ewrite_super call in generic_shutdown_super\n\nWe just did a full fs writeout using sync_filesystem before, and if\nthat\u0027s not enough for the filesystem it can perform it\u0027s own writeout\nin -\u003eput_super, which many filesystems already do.\n\nMove a call to foofs_write_super into every foofs_put_super for now to\nguarantee identical behaviour until it\u0027s cleaned up by the individual\nfilesystem maintainers.\n\nExceptions:\n\n -
