Subject: [PATCH v2 03/10] block/raw-format: implement .bdrv_cancel_in_flight handler
Date: Fri,  5 Feb 2021 19:37:13 +0300	[thread overview]
Message-ID: <20210205163720.887197-4-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20210205163720.887197-1-vsementsov@virtuozzo.com>

We are going to cancel in-flight requests on mirror nbd target on job
cancel. Still nbd is often used not directly but as raw-format child.
So, add pass-through handler here.
