Subject: [PATCH v2 2/6] block/nbd-client: drop max_block restriction from discard
Date: Wed, 1 Apr 2020 18:01:08 +0300 [thread overview]
Message-ID: <20200401150112.9557-3-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20200401150112.9557-1-vsementsov@virtuozzo.com>
NBD spec is updated, so that max_block doesn't relate to
NBD_CMD_TRIM. So, drop the restriction.
