Currently, fair share from hctx_may_queue() requires two

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?

Of course, I'll try to send a RFC patch.

Thanks,
Kuai

Thanks,

Bart.
