    Subject[patch 114/123] dm ioctl: only issue uevent on resume if state changed
    2.6.33-stable review patch.  If anyone has any objections, please let me know.

    -----------------

    From: Mike Snitzer <snitzer@redhat.com>

    commit 0f3649a9e305ea22eb196a84a2d7520afcaa6060 upstream.

    Only issue a uevent on a resume if the state of the device changed,
    i.e. if it was suspended and/or its table was replaced.
