Subject: blk-mq: remove extra requeue trace
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=74814b1c5569f5503727cf3052a52e2349818409;p=deliverable%2Flinux.git

blk-mq: remove extra requeue trace

We already issue a blktrace requeue event in
__blk_mq_requeue_request(), don't do it from the original caller
as well.
