Subject: pktcdvd: remove queue_lock around blk_queue_max_hw_sectors
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a50f9aec1ac713dd25f1b1b443d97aa2fc69f740;p=linux.git

pktcdvd: remove queue_lock around blk_queue_max_hw_sectors

blk_queue_max_hw_sectors can't do anything with queue_lock protection
so don't hold it.
