Subject: [PATCH v13 3/9] nvme: Move nvme_passthru_[start|end]() calls to common helper
Date: Thu, 14 May 2020 11:22:47 -0600 [thread overview]
Message-ID: <20200514172253.6445-4-logang@deltatee.com> (raw)
In-Reply-To: <20200514172253.6445-1-logang@deltatee.com>
Introduce a new nvme_execute_passthru_rq() helper which calls
nvme_passthru_[start|end]() around blk_execute_rq(). This ensures
all passthru calls (including nvme_submit_io()) will be wrapped
appropriately.
nvme_execute_passthru_rq() will also be useful for the nvmet passthru
code.
