Subject: [PATCH 03/14] block/blk-rq-qos: Move a function from a header file into a C file
Date: Tue, 8 Jun 2021 16:06:52 -0700 [thread overview]
Message-ID: <20210608230703.19510-4-bvanassche@acm.org> (raw)
In-Reply-To: <20210608230703.19510-1-bvanassche@acm.org>
rq_qos_id_to_name() is not in the hot path so move it from a .h into a .c
file.
