Subject: [PATCH 2/5] block/nbd-client: drop max_block restriction from discard
Date: Mon, 2 Mar 2020 13:05:34 +0300 [thread overview]
Message-ID: <20200302100537.29058-3-vsementsov@virtuozzo.com> (raw)
In-Reply-To: <20200302100537.29058-1-vsementsov@virtuozzo.com>
NBD spec is updated, so that max_block doesn't relate to
NBD_CMD_TRIM. So, drop the restriction.
