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": "f24075bd0c1cd1cc2cf86d394f960aa0401de573", "tree": "609ad9884e43a8bb1ba5834996955a06bef66fa2", "parents": [ "a11f3a0574a5734db3e5de38922430d005d35118" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Mar 23 03:00:34 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Mar 23 07:38:12 2006 -0800" }, "message": "[PATCH] sem2mutex: iprune\n\nSemaphore to mutex conversion.\n\nThe conversion was generated via scripts, and the result was validated\nautomatically via a script as well.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "d4f9af9dac4ecb75818f909168f87b441cc95653", "tree": "c5b0ccf7705b6ef0739fd5af64cf48c092760013", "parents": [ "d3be915fc5e7d19a2283ad9b0fe0782a74675d0a" ], "author": { "name": "Ingo Molnar", "email": "mingo@elte.hu", "time": "Thu Mar 23 03:00:30 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Thu Mar 23 07:38:11 2006 -0800" }, "message": "[PATCH] sem2mutex: inotify\n\nSemaphore to mutex conversion.\n\nThe conversion was generated via scripts, and the result was validated\nautomatically via a script as well.\n\nSigned-off-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: John McCutchan \u003cttb@tentacle.dhs.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nAcked-by: Robert Love \u003crml@novell.com\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "b5173119ff10c5538e92a7957a50887ae170b8da", "tree": "5b5af4e03e627b66a9f37d25dd370a145ec72438", "parents": [ "8e08b756869eeb08ace17ad64c2a8cb97b18e856" ], "author": { "name": "Robert Love", "email": "rml@novell.com", "time": "Tue Feb 07 12:58:45 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Tue Feb 07 16:12:33 2006 -0800" }, "message": "[PATCH] inotify: fix one-shot support\n\nFix one-shot support in inotify.

This quickly results in too many\n open files and pins removable media, preventing unmount.\n * dnotify is directory-based. You only learn about changes to\n directories. Sure, a change to a file in a directory affects\n the directory, but you are then forced to keep a cache of\n stat structures.\n * dnotify\u0027s interface to user-space is awful. Signals?\n\ninotify provides a more usable, simple, powerful solution to file change\nnotification:\n\n * inotify\u0027s interface is a system call that returns a fd, not SIGIO.\n\t You get a single fd, which is select()-able.\n * inotify has an event that says \"the filesystem that the item\n you were watching is on was unmounted.\"\n * inotify can watch directories or files.\n\nInotify is currently used by Beagle (a desktop search infrastructure),\nGamin (a FAM replacement), and other projects.\n\nSee Documentation/filesystems/inotify.txt.\n\nSigned-off-by: Robert Love \u003crml@novell.com\u003e\nCc: John McCutchan \u003cttb@tentacle.dhs.org\u003e\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ] }
