cgroup: Avoid -Wstringop-overflow warnings (2023-08-17 11:55:05 -1000)
----------------------------------------------------------------
cgroup: Changes for v6.6
* Per-cpu cpu usage stats are now tracked. This currently isn't printed out
in the cgroupfs interface and can only be accessed through e.g. BPF.
Should decide on a not-too-ugly way to show per-cpu stats in cgroupfs.
* cpuset received some cleanups and prepatory patches for the pending
cpus.exclusive patchset which will allow cpuset partitions to be created
below non-partition parents, which should ease the management of partition
cpusets.
* A lot of code and documentation cleanup patches.
* tools/testing/selftests/cgroup/test_cpuset.c is added. This causes trivial
conflicts in .gitignore and Makefile under the directory against
fe3b1bf19bdf ("selftests: cgroup: add test_zswap program"). They can be
resolved by keeping lines from both branches.
