Subject: [PATCH v4 2/6] block: make request_to_qc_t public
Date: Fri, 14 Dec 2018 11:06:06 -0800	[thread overview]
Message-ID: <20181214190610.20086-3-sagi@grimberg.me> (raw)
In-Reply-To: <20181214190610.20086-1-sagi@grimberg.me>

block consumers will need it for polling requests that
are sent with blk_execute_rq_nowait. Also, get rid of
blk_tag_to_qc_t and open-code it instead.
