Greeting,

FYI, we noticed a -21.4% regression of fxmark.hdd_f2fs_dbench_client_72_directio.works/sec due to commit:

commit: 658f2fb7d2139d7a218083b7e8688dd288c6512d ("[PATCH] block: fix io hung by block throttle")
url: https://github.com/0day-ci/linux/commits/Junxiao-Bi/block-fix-io-hung-by-block-throttle/20210415-052219
base: https://git.kernel.org/cgit/linux/kernel/git/axboe/linux-block.git for-next

in testcase: fxmark
on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory
with following parameters:

disk: 1HDD
media: hdd
test: dbench_client
fstype: f2fs
directio: directio

This test is doing directio? The throttle didn't take care direct io, see wbt_should_throttle(), in that case, the changed code will not even be run.

Thanks,

Junxiao.
