I'll provide null_blk tests result in the next version if anyone thinks
the approch is acceptable:

1) add a new field 'available_tags' and update it in slow path, hence
fast path hctx_may_queue() won't be affected.
2) delay tag sharing untill failed to get driver tag;
3) add a timer per shared tags to balance shared tags;
 My concern is that the complexity of the algorithm introduced by that patch
series is significant. I prefer code that is easy to understand. This is why
I haven't started yet with a detailed review. If anyone else wants to review
that patch series that's fine with me.

Thanks,
