2009-06-11fsnotify: allow groups to set freeing_mark to nullEric Paris
Most fsnotify listeners (all but inotify) do not care about marks being freed. Allow groups to set freeing_mark to null and do not call any function if it is set that way. Signed-off-by: Eric Paris <eparis@redhat.com>
2009-06-11inotify/dnotify: should_send_event shouldn't match on FS_EVENT_ON_CHILDEric Paris
inotify and dnotify will both indicate that they want any event which came from a child inode. The fix is to mask off FS_EVENT_ON_CHILD when deciding if inotify or dnotify is interested in a given event. Signed-off-by: Eric Paris <eparis@redhat.com>
2009-06-11dnotify: do not bother to lock entry->lock when reading maskEric Paris
entry->lock is needed to make sure entry->mask does not change while manipulating it. In dnotify_should_send_event() we don't care if we get an old or a new mask value out of this entry so there is no point it taking the lock. Signed-off-by: Eric Paris <eparis@redhat.com>
2009-06-11dnotify: do not use ?true:false when assigning to a boolEric Paris
dnotify_should send event assigned a bool using ?true:false when computing a bit operation. This is poitless and the bool type does this for us. Signed-off-by: Eric Paris <eparis@redhat.com>
2009-06-11fsnotify: allow groups to add private data to eventsEric Paris
inotify needs per group information attached to events. This patch allows groups to attach private information and implements a callback so that information can be freed when an event is being destroyed.

2008-12-31filesystem notification: create fs/notify to contain all fs notificationEric Paris
Creating a generic filesystem notification interface, fsnotify, which will be used by inotify, dnotify, and eventually fanotify is really starting to clutter the fs directory. This patch simply moves inotify and dnotify into fs/notify/inotify and fs/notify/dnotify respectively to make both current fs/ and future notification tidier.
