Subject: [PULL 26/31] block/parallels: BDRVParallelsState: add cluster_size field
Date: Fri, 5 Mar 2021 17:54:49 +0100 [thread overview]
Message-ID: <20210305165454.356840-27-kwolf@redhat.com> (raw)
In-Reply-To: <20210305165454.356840-1-kwolf@redhat.com>
From: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>
We are going to use it in more places, calculating
"s->tracks << BDRV_SECTOR_BITS" doesn't look good.
