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).

As well as for the base components of any\nabsolute pathname, even if you are the owner of the final file.\n\n[ At some point we probably want to move this ACL caching logic entirely\n into the VFS layer (and only call down to the filesystem when\n uncached), but in the meantime this improves ext3 a bit.\n\n A similar fix to btrfs makes a much bigger difference (15x improvement\n in lmbench) due to broken caching. ]\n\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\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 - current_umask()\n\ncurrent-\u003efs-\u003eumask is what most of fs_struct users are doing.\nPut that into a helper function.\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "e6305c43eda10ebfd2ad9e35d6e172ccc7bb3695", "tree": "8a95bd0e27fb3ce895cca9ef91af2e1605e4cdab", "parents": [ "1bd5191d9f5d1928c4efdf604c4164b04bb88dbe" ], "author": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Tue Jul 15 21:03:57 2008 -0400" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Sat Jul 26 20:53:14 2008 -0400" }, "message": "[PATCH] sanitize -\u003epermission() prototype\n\n* kill nameidata * argument; map the 3 bits in -\u003eflags anybody cares\n about to new MAY_... ones and pass with the mask.\n* kill redundant gfs2_iop_permission()\n* sanitize ecryptfs_permission()\n* fix remaining places where -\u003epermission() instances might barf on new\n MAY_... found in mask.\n\nThe obvious next target in that direction is permission(9)\n\nfolded fix for nfs_permission() breakage from Miklos Szeredi \u003cmszeredi@suse.cz\u003e\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "c587f0c0a69227587baaa12e75815b6644457c0a", "tree": "5ef93bd6d73fdab6084de20988b8934dbc10ae08", "parents": [ "ffda6857c87fbe3ab144ff3f34b89421eed048cf" ], "author": { "name": "Josef Bacik", "email": "jbacik@redhat.com", "time": "Wed Mar 19 17:00:49 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Wed Mar 19 18:53:36 2008 -0700" }, "message": "ext3: fix wrong gfp type under transaction\n\nThere are several places where we make allocations with GFP_KERNEL while under\na transaction, which could lead to an assertion panic or lockup if under\nmemory pressure.
