@gitPo1son @zhongchanghui Thanks for this PR. As I noted in the issue #219, I would like to ask the confirmation by Yu Kuai. Also, this commit needs proper commit log. Its title should have a prefix, like, "throtl/rc: ...". And the commit message should summarize what is reported in the issue #219. If that helps, I can do such commit message edit. |

Hi, @kawasaki yes, you are right, my test kernel has CONFIG_HZ=100. Thanks， |
when kernel set CONFIG_HZ=100,throtl/001 will failed on the sdebug device, due to 1 jiffy delay for each I/O takes 0.01 second,then 256 I/Os takes around 2.56 seconds which is reported as 3 seconds, making the expected 1 second test actually take 3 seconds.
