v4:
- Add missing rcu_read_lock/unlock to cpuset_cancel_fork() in patch 3.
- Add patch 5 to reduce performance impact for the
non-CLONE_INTO_CGROUP case.
v3:
- Update patches 2 & 3 to put task_cs() call under rcu_read_lock().
v2:
- Drop v1 patch 3
- Add a new patch to fix an issue in cpuset_cancel_attach() and
another patch to add cpuset_can_fork() and cpuset_cacnel_fork()
methods.
The first patch in this series fixes a problem in
cpuset_cancel_attach(). Patches 2 and 3 fixes the CLONE_INTO_CGROUP
problem in cpuset. Patch 4 is a minor fix. The last patch is a
performance optimization patch for the non-CLONE_INTO_CGROUP case.
Waiman Long (5):
cgroup/cpuset: Wake up cpuset_attach_wq tasks in
cpuset_cancel_attach()
cgroup/cpuset: Make cpuset_fork() handle CLONE_INTO_CGROUP properly
cgroup/cpuset: Add cpuset_can_fork() and cpuset_cancel_fork() methods
cgroup/cpuset: Make cpuset_attach_task() skip subpartitions CPUs for
top_cpuset
cgroup/cpuset: Optimize out unneeded
cpuset_can_fork/cpuset_cancel_fork calls
