Subject: [PATCH v2 0/4] cgroup/cpuset: Miscellaneous updates
Date: Fri, 17 Mar 2023 11:15:04 -0400	[thread overview]
Message-ID: <20230317151508.1225282-1-longman@redhat.com> (raw)

 v2:
  - Add a new patch 1 that fixes a bug introduced by recent v6.2 commit
    7a2127e66a00 ("cpuset: Call set_cpus_allowed_ptr() with appropriate
    mask for task").
  - Make a small twist and additional comment to patch 2 ("cgroup/cpuset:
    Skip task update if hotplug doesn't affect current cpuset") as
    suggested by Michal.
  - Remove v1 patches 3/4 for now for further discussion.

This patch series includes miscellaneous update to the cpuset and its
testing code.

Patch 1 fixes a bug caused by commit 7a2127e66a00 ("cpuset: Call
set_cpus_allowed_ptr() with appropriate mask for task") in the partition
handling code. This fix was verified by running the test_cpuset_prs.sh
test.

Patch 2 is for a hotplug optimization.

Patch 3 is actually a follow-up of commit 3fb906e7fabb ("cgroup/cpuset:
Don't filter offline CPUs in cpuset_cpus_allowed() for top cpuset tasks").

Patch 4 reduces verbosity when running test_cpuset_prs.sh test script
unless explicitly enabled with the -v option.

Waiman Long (4):
  cgroup/cpuset: Fix partition root's cpuset.cpus update bug
  cgroup/cpuset: Skip task update if hotplug doesn't affect current
    cpuset
  cgroup/cpuset: Include offline CPUs when tasks' cpumasks in top_cpuset
    are updated
  cgroup/cpuset: Minor updates to test_cpuset_prs.sh
