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" * tag 'block-5.16-2021-12-19' of git://git.kernel.dk/linux-block: Revert "block: reduce kblockd_mod_delayed_work_on() CPU consumption"
