      fsnotify: allow groups to set freeing_mark to null · a092ee20
      Eric Paris authored
      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.

      inotify/dnotify: should_send_event shouldn't match on FS_EVENT_ON_CHILD · e42e2773
      Eric Paris authored
      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.

      dnotify: do not bother to lock entry->lock when reading mask · ce61856b
      Eric Paris authored
      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.

      fsnotify: move events should indicate the event was on a child · ff52cc21
      Eric Paris authored
      fsnotify tells its listeners explicitly when an event happened on the given
      inode verses on the child of the given inode.  (see __fsnotify_parent)
      However, the semantics of fsnotify_move() are such that we deliver events
      directly to the two parent directories in question (old_dir and new_dir)
      directly without using the __fsnotify_parent() call.  fsnotify should be
      adding FS_EVENT_ON_CHILD for the notifications to these parents.

      inotify: reimplement inotify using fsnotify · 63c882a0
      Eric Paris authored
      Reimplement inotify_user using fsnotify.  This should be feature for feature
      exactly the same as the original inotify_user.  This does not make any changes
      to the in kernel inotify feature used by audit.  Those patches (and the eventual
      removal of in kernel inotify) will come after the new inotify_user proves to be
      working correctly.

      fsnotify: handle filesystem unmounts with fsnotify marks · 164bc619
      Eric Paris authored
      When an fs is unmounted with an fsnotify mark entry attached to one of its
      inodes we need to destroy that mark entry and we also (like inotify) send
      an unmount event.

      fsnotify: fsnotify marks on inodes pin them in core · 1ef5f13c
      Eric Paris authored
      This patch pins any inodes with an fsnotify mark in core.  The idea is that
      as soon as the mark is removed from the inode->fsnotify_mark_entries list
      the inode will be iput.  In reality is doesn't quite work exactly this way.
      The igrab will happen when the mark is added to an inode, but the iput will
      happen when the inode pointer is NULL'd inside the mark.
      
      It's possible that 2 racing things will try to remove the mark from
      different directions.  One may try to remove the mark because of an
      explicit request and one might try to remove it because the inode was
      deleted.  It's possible that the removal because of inode deletion will
      remove the mark from the inode's list, but the removal by explicit request
      will actually set entry->inode == NULL; and call the iput.  This is safe.

      fsnotify: add correlations between events · 47882c6f
      Eric Paris authored
      As part of the standard inotify events it includes a correlation cookie
      between two dentry move operations.  This patch includes the same behaviour
      in fsnotify events.  It is needed so that inotify userspace can be
      implemented on top of fsnotify.

      fsnotify: generic notification queue and waitq · a2d8bc6c
      Eric Paris authored
      inotify needs to do asyc notification in which event information is stored
      on a queue until the listener is ready to receive it.  This patch
      implements a generic notification queue for inotify (and later fanotify) to
      store events to be sent at a later time.
