That\u0027s fine if we have a hold on inode; however, for all\nother cases we need to make damn sure we don\u0027t race with umount. We can\n*NOT* just grab a reference to a watch - inotify_unmount_inodes() will\nhappily sail past it and we\u0027ll end with reference to inode potentially\noutliving its superblock.\n\nIdeally we just want to grab an active reference to superblock if we\ncan; that will make sure we won\u0027t go into inotify_umount_inodes() until\nwe are done. Cleanup is just deactivate_super().\n\nHowever, that leaves a messy case - what if we *are* racing with\numount() and active references to superblock can\u0027t be acquired anymore?\nWe can bump -\u003es_count, grab -\u003es_umount, which will almost certainly wait\nuntil the superblock is shut down and the watch in question is pining\nfor fjords. That\u0027s fine, but there is a problem - we might have hit the\nwindow between -\u003es_active getting to 0 / -\u003es_count - below S_BIAS (i.e.\nthe moment when superblock is past the point of no return and is heading\nfor shutdown) and the moment when deactivate_super() acquires\n-\u003es_umount.\n\nWe could just do drop_super() yield() and retry, but that\u0027s rather\nantisocial and this stuff is luser-triggerable. OTOH, having grabbed\n-\u003es_umount and having found that we\u0027d got there first (i.e. that\n-\u003es_root is non-NULL) we know that we won\u0027t race with\ninotify_umount_inodes().\n\nSo we could grab a reference to watch and do the rest as above, just\nwith drop_super() instead of deactivate_super(), right? Wrong. We had\nto drop ih-\u003emutex before we could grab -\u003es_umount. So the watch\ncould\u0027ve been gone already.\n\nThat still can be dealt with - we need to save watch-\u003ewd, do idr_find()\nand compare its result with our pointer. If they match, we either have\nthe damn thing still alive or we\u0027d lost not one but two races at once,\nthe watch had been killed and a new one got created with the same -\u003ewd\nat the same address. That couldn\u0027t have happened in inotify_destroy(),\nbut inotify_rm_wd() could run into that. Still, \"new one got created\"\nis not a problem - we have every right to kill it or leave it alone,\nwhatever\u0027s more convenient.\n\nSo we can use idr_find(...) \u003d\u003d watch \u0026\u0026 watch-\u003einode-\u003ei_sb \u003d\u003d sb as\n\"grab it and kill it\" check.

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" }, { "commit": "8140a5005bc6f1c9d0fa103460d50d472e6e3426", "tree": "9c5ae431bf1db43e3a1e7a4cceb472c76077ac18", "parents": [ "b4788f6d55548e587ced330ece711456f40ec8f1" ], "author": { "name": "John McCutchan", "email": "ttb@tentacle.dhs.org", "time": "Mon Dec 12 00:37:14 2005 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Dec 12 08:57:43 2005 -0800" }, "message": "[PATCH] inotify: add two inotify_add_watch flags\n\nThe below patch lets userspace have more control over the inodes that\ninotify will watch.
