Jinke, is the case you described in the original email what you actually saw
in production or a simplified test case for demonstration? If the latter,
can you describe actual problems seen in production?
Thanks.
Hi
In our internal scenario, iocost has been deployed as the main io
isolation method and is gradually spreading。
But for some specific scenarios with old kernel versions, blk-throtl
is alose needed. The scenario described in my email is in the early
stage of research and extensive testing for it. During this period，some
priority inversion issues amoug cgroups or within one cgroup have been
observed. So I send this patch to try to fix or mitigate some of these
issues.
Thanks
Jinke
