Subject: [PATCH -next 0/4] some optimization for cpuset
Date: Fri, 8 Aug 2025 09:25:11 +0000 [thread overview]
Message-ID: <20250808092515.764820-1-chenridong@huaweicloud.com> (raw)
From: Chen Ridong <chenridong@huawei.com>
This patch series includes the following improvements:
1. Removes the redundant CS_ONLINE flag.
2. Introduces new helper functions guard_cpuset() and
guard_cpus_read_and_cpuset().
3. Replaces manual locking patterns with the new guard helpers.
Chen Ridong (4):
cpuset: remove redundant CS_ONLINE flag
cpuset: add helpers for cpuset related locks
cpuset: use guard_cpus_read_and_cpuset to make code concise
cpuset: replace cpuset_lock() with guard_cpuset()
