Subject: [PATCH V3 3/6] nvmet: remove op_flags for passthru commands
Date: Wed, 21 Oct 2020 18:02:31 -0700
Message-ID: <20201022010234.8304-4-chaitanya.kulkarni@wdc.com> (raw)
In-Reply-To: <20201022010234.8304-1-chaitanya.kulkarni@wdc.com>

For passthru commands setting op_flags has no meaning. Remove the code
that sets the op flags in nvmet_passthru_map_sg().
