Yeah, I fully aware the RFC-marked patches would clash with your
works. I will surely rework them if the proposal considered

Hi Alex,
this clashes badly with the my queue mapping rework that went into
Jens tree recently.
But in the meantime: there seem to be lots of little bugfixes and
cleanups in the series, any chance you could send them out as a first
series while updating the rest?
Also please Cc the linux-block

Linux block device layer limits number of hardware contexts queues
to number of CPUs in the system. That looks like suboptimal hardware
utilization in systems where number of CPUs is (significantly) less
than number of hardware queues.
In addition, there is a need to deal with tag starvation (see
