Subject: workqueue: fix a piece of comment about reserved bits for work flags
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c39ba6b3a8d47be07c180f857564a25a0356d336;p=linux.git

workqueue: fix a piece of comment about reserved bits for work flags

8a2e8e5dec7e("workqueue: fix cwq->nr_active underflow")
allocated one more bit from the work flags, and it updated
partial of the comments (128 bytes -> 256 bytes), but it
failed to update the info about the number of reserved bits.
