Subject: [PULL 14/22] vmdk: Fix .bdrv_co_create(_opts) to open images with no_co_wrapper
Date: Fri, 17 Feb 2023 16:09:46 +0100	[thread overview]
Message-ID: <20230217150954.283920-14-kwolf@redhat.com> (raw)
In-Reply-To: <20230217150954.283920-1-kwolf@redhat.com>

.bdrv_co_create implementations run in a coroutine. Therefore they are
not allowed to open images directly. Fix the calls to use the
corresponding no_co_wrappers instead.
