commit 1728dd23f74b9d01df5146e9b405c3149b896bc7
Author: David Teigland <teigland@redhat.com>
Date:   Mon May 5 13:43:16 2008 -0500

    lock_dlm: ignore dlm EBUSY on plock unlock
    
    bz 432707
    
    The previous commit for this bug didn't resolve all the cases of
    EBUSY assertions from plock unlocks.  As suggested in the previous
    commit message, this patch just ignores -EBUSY errors returned for
    plock unlocks instead of asserting.
