Subject: [PATCH 00/10] cgroup/cpuset: Miscellaneous partition bug fixes and enhancements
Date: Sun, 30 Mar 2025 17:52:38 -0400	[thread overview]
Message-ID: <20250330215248.3620801-1-longman@redhat.com> (raw)

This patch series fixes a number of bugs in the cpuset partition code as
well as improvement in remote partition handling. The test_cpuset_prs.sh
is also enhanced to allow more vigorous remote partition testing.

Waiman Long (10):
  cgroup/cpuset: Fix race between newly created partition and dying one
  cgroup/cpuset: Fix incorrect isolated_cpus update in
    update_parent_effective_cpumask()
  cgroup/cpuset: Fix error handling in remote_partition_disable()
  cgroup/cpuset: Remove remote_partition_check() & make
    update_cpumasks_hier() handle remote partition
  cgroup/cpuset: Don't allow creation of local partition over a remote
    one
  cgroup/cpuset: Code cleanup and comment update
  cgroup/cpuset: Remove unneeded goto in sched_partition_write() and
    rename it
  selftest/cgroup: Update test_cpuset_prs.sh to use | as effective CPUs
    and state separator
  selftest/cgroup: Clean up and restructure test_cpuset_prs.sh
  selftest/cgroup: Add a remote partition transition test to
    test_cpuset_prs.sh
