Subject: [PATCH v3 08/10] block/vhdx: drop unallocated_blocks_are_zero
Date: Thu, 28 May 2020 12:44:03 +0300 [thread overview]
Message-ID: <20200528094405.145708-9-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20200528094405.145708-1-vsementsov@virtuozzo.com>
vhdx doesn't have .bdrv_co_block_status handler, so DATA|ALLOCATED is
always assumed for it in bdrv_co_block_status().
unallocated_blocks_are_zero is useless (it doesn't affect the only user
of the field: bdrv_co_block_status()), drop it.
