[PATCH] Skip check for mandatory locks when unlocking
ocfs2_lock() will skip locks on file which has mode set to 02666. This
is a problem in cases where the mode of the file is changed after a
process has obtained a lock on the file.
ocfs2_lock() should skip the check for mandatory locks when unlocking a
file.
