Currently, fair share from hctx_may_queue() requires two atomic_read(active_queues and active_requests), I think this smoothing method can be placed into get_tag fail path, for example, the more times a disk failed to get tag in a period of time, the more tag this disk can get, and all the information can be updated here(perhaps directly record how many tags a disk can get, then hctx_may_queue() still only require 2 atomic_read()).
That sounds interesting to me. Do you perhaps plan to implement this approach and to post it as a patch?
Thanks, Bart.
