Subject: futex: Drop leftover wake_q_add() comment
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=751459043cc87c3f0098034b15ca5252d12539ab;p=linux.git

futex: Drop leftover wake_q_add() comment

Since the original comment, we have moved to do the task
reference counting explicitly along with wake_q_add_safe().
Drop the now incorrect comment.
