Subject: [PULL 08/30] block/io: bdrv_wait_serialising_requests_locked: drop extra bs arg
Date: Fri, 18 Dec 2020 16:12:27 +0100 [thread overview]
Message-ID: <20201218151249.715731-9-mreitz@redhat.com> (raw)
In-Reply-To: <20201218151249.715731-1-mreitz@redhat.com>
From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
bs is linked in req, so no needs to pass it separately. Most of
tracked-requests API doesn't have bs argument. Actually, after this
patch only tracked_request_begin has it, but it's for purpose.
While being here, also add a comment about what "_locked" is.
