Subject: [PATCH v2 0/2] Make blk_mq_map_queues() return void
Date: Mon, 15 Aug 2022 10:00:41 -0700 [thread overview]
Message-ID: <20220815170043.19489-1-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.
Changes compared to v1:
- Combined all patches except one into a single patch as requested by Christoph.

null_blk: Modify the behavior of null_map_queues()
