Merge tag 'block-5.16-2021-12-19' of git://git.kernel.dk/linux-block
Pull block revert from Jens Axboe:
"It turns out that the fix for not hammering on the delayed work timer
too much caused a performance regression for BFQ, so let's revert the
change for now.
I've got some ideas on how to fix it appropriately, but they should
wait for 5.17"
