Subject: [PULL 03/23] test-block-iothread: Lock AioContext for blk_insert_bs()
Date: Wed, 28 Jun 2023 16:15:06 +0200	[thread overview]
Message-ID: <20230628141526.293104-4-kwolf@redhat.com> (raw)
In-Reply-To: <20230628141526.293104-1-kwolf@redhat.com>

blk_insert_bs() requires that callers hold the AioContext lock for the
node that should be inserted. Take it.
