Subject: block/bfq-iosched.c: use "false" rather than "BLK_RW_ASYNC"
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=37a744a068c99903c52f959907ea5135f8ce4ad6;p=linux.git

block/bfq-iosched.c: use "false" rather than "BLK_RW_ASYNC"

[ Upstream commit f6bad159f5d5e5b33531aba3d9b860ad8618afe0 ]

bfq_get_queue() expects a "bool" for the third arg, so pass "false"
rather than "BLK_RW_ASYNC" which will soon be removed.
