Subject: [PULL 03/34] co-queue: drop extra coroutine_fn marks
Date: Tue, 15 Jun 2021 15:47:25 -0500 [thread overview]
Message-ID: <20210615204756.281505-4-eblake@redhat.com> (raw)
In-Reply-To: <20210615204756.281505-1-eblake@redhat.com>
From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
qemu_co_queue_next() and qemu_co_queue_restart_all() just call
aio_co_wake() which works well in non-coroutine context. So these
functions can be called from non-coroutine context as well. And
actually qemu_co_queue_restart_all() is called from
nbd_cancel_in_flight(), which is called from non-coroutine context.
