Subject: [Qemu-devel] [PATCH v2 01/13] block-backend: Make blk_inc/dec_in_flight public
Date: Wed, 20 Feb 2019 18:48:31 +0100 [thread overview]
Message-ID: <20190220174843.8847-2-kwolf@redhat.com> (raw)
In-Reply-To: <20190220174843.8847-1-kwolf@redhat.com>
For some users of BlockBackends, just increasing the in_flight counter
is easier than implementing separate handlers in BlockDevOps. Make the
helper functions for this public.
