    Subject[PATCH -v1 00/11] fsnotify: unified filesystem notification backend
    From
    Date
    Whoops, forgot the cover note. So proceeding is an implementation of
    fsnotify, a novel unified filesystem notification backend. This patch
    set implements the backend and converts both dnotify and inotify to this
    backend. This patch set reduced the size of struct inode if one uses
    both dnotify and inotify.

    I have patches which move the audit functionality which uses inotify to
    fsnotify and I have patches which implement fanotify, my new on access
    notification and access decisions to this backend, but just to keep the
    series small I'm only sending fsnotify, dnotify and inotify changes.

    I would love the most careful and scrutinizing eyes on patches 3, 9, 10
    which implement the changes to inodes and introduce by far the most
    complex locking, refcnt, and object lifetimes.

    dnotify changes are in patch 5
    inotify changes are in patch 11
