blk-mq-sched: alloate reserved tags out of normal pool At least one driver, mtip32xx, has a hard coded dependency on the value of the reserved tag used for internal commands. While that should really be fixed up, for now let's ensure that we just bypass the scheduler tags an allocation marked as reserved. They are used for house keeping or error handling, so we can safely ignore them in the scheduler. Tested-by: Ming Lei <ming.lei@redhat.com> Signed-off-by: Jens Axboe <axboe@fb.com>
