Re: blk-mq: allow passing in an external queue mapping V3

Thanks for all the testing and the review Keith, as well as the
fixes earlier.

Jens, what do you think of the series?

Thomas has added the first 5 patches to

https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git/log/?h=irq/for-block

so it would be great if we could pull that into a block branch and
get the rest into the block tree sooner or later.
