Subject: [PATCH 0/6] Make blk_mq_map_queues() return void
Date: Fri, 12 Aug 2022 14:07:54 -0700	[thread overview]
Message-ID: <20220812210800.2253972-1-bvanassche@acm.org> (raw)

Hi Jens,

The only block driver for which the .map_queues() callback can fail is null_blk. Since
most blk_mq_map_queues() callers ignore the return value of this function, modify the
null_blk driver such that its .map_queues() callback does not fail and change the
blk_mq_map_queues() return type into void.

Please consider this patch series for the next merge window.

Thanks,

Bart.
