Subject: [PATCH -next v3 0/3] some optimization for cpuset

From: Chen Ridong <chenridong@...wei.com>

This patch series contains several cpuset improvements:

1. Decouple cpuset and tmpmasks allocation/freeing.
2. Add cpuset_full_[un]lock helpers.

---
v3:
 - fix typos and comment errors.
 - rename cpus_read_cpuset_[un]lock to cpuset_full_[un]lock

v2:
 - dropped guard helper approach, nusing new helper instead.
 - added patches for decoupling cpuset/tmpmasks allocation

Chen Ridong (3):
  cpuset: decouple tmpmasks and cpumasks freeing in cgroup
  cpuset: separate tmpmasks and cpuset allocation logic
  cpuset: add helpers for cpus read and cpuset_mutex locks
