    inotify: do not leak inode marks in inotify_add_watch · 75fe2b26
    Eric Paris authored
    inotify_add_watch had a couple of problems.  The biggest being that if
    inotify_add_watch was called on the same inode twice (to update or change the
    event mask) a refence was taken on the original inode mark by
    fsnotify_find_mark_entry but was not being dropped at the end of the
    inotify_add_watch call.  Thus if inotify_rm_watch was called although the mark
    was removed from the inode, the refcnt wouldn't hit zero and we would leak
    memory.
