Subject: [PATCH 0/2] Remove blk_mq_sched_started_request function

While inspecting the queue_rq calling sites, I verified that
blk_mq_start_request calls blk_mq_sched_started_request, and this function
checks if the elevator of the current request implements the started_request,
but currently none of the available IO schedulers do.

So, let's remove blk_mq_sched_started_request along with started_request, which
is member of the elevator_mq_ops struct.

Marcos Paulo de Souza (2):
  block: blk-mq: Remove blk_mq_sched_started_request function
  include: elevator.h: Remove started_request from elevator_mq_ops
