Merge tag 'cgroup-for-7.1-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fixes from Tejun Heo:
"One cpuset fix and a maintenance update, both low-risk:
- Fix cpuset partition CPU accounting under sibling CPU exclusion
that could produce wrong CPU assignments and trigger
scheduling-domain warnings. Includes selftests.
- Update an email address in MAINTAINERS"
* tag 'cgroup-for-7.1-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
cgroup/cpuset: Change Ridong's email
cgroup/cpuset: Add test cases for sibling CPU exclusion on partition update
cgroup/cpuset: Use effective_xcpus in partcmd_update add/del mask calculation
