X-Git-Tag: v4.9.8~5649^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=986c01942afb8eb6cc1708e721292db23b715d4e;p=platform%2Fkernel%2Flinux-rpi3.git

fold unlocking the children into dentry_unlock_parents_for_move()

... renaming it into dentry_unlock_for_move() and making it more
symmetric with dentry_lock_for_move().
