There are 3 places where the cpu and node masks of the top cpuset can be initialized in the order they are executed: 1) start_kernel -> cpuset_init() 2) start_kernel -> cgroup_init() -> cpuset_bind() 3) kernel_init_freeable() -> do_basic_setup() -> cpuset_init_smp()

The first cpuset_init() function just sets all the bits in the masks. The last one executed is cpuset_init_smp() which sets up cpu and node masks suitable for v1, but not v2. cpuset_bind() does the right setup for both v1 and v2 assuming that effective_mems and effective_cpus have been set up properly which is not strictly the case here. As a result, cpu and memory node hot add may fail to update the cpu and node masks of the top cpuset to include the newly added cpu or node in a cgroup v2 environment.

To fix this problem, the redundant cpus_allowed and mems_allowed mask setup in cpuset_init_smp() are removed. The effective_cpus and effective_mems setup there are moved to cpuset_bind().

Hi Waiman,

Thanks for the patch!

IIUC, the init order is: cpuset_bind() smp_init() cpuset_init_smp()

while all cpus except boot cpu is brought up in smp_init(), so I'm thinking moving the cpus_allowed init from cpuset_init_smp() to cpuset_bind() may cause some problem.

Thanks, Feng

Good point. So cpuset_init_smp() is still useful for setting the right effective_cpus and probably effective_mems. I will update the patch accordingly.

Greeting,

FYI, we noticed a 2583.0% regression of kbuild.buildtime_per_iteration due to commit:

commit: 7aaa45f8374887d98cd479a6bdd3b4c74e6a981a ("[PATCH] cgroup/cpuset: Remove redundant cpu/node masks setup in cpuset_init_smp()") url: https://github.com/intel-lab-lkp/linux/commits/Waiman-Long/cgroup-cpuset-Rem... base: https://git.kernel.org/cgit/linux/kernel/git/tj/cgroup.git for-next patch link: https://lore.kernel.org/linux-mm/20220425020926.1264611-1-longman@redhat.com

That link is the original v1 patch which is not correct. Is this the one that is being tested here?

I have sent out another patch which shouldn't cause this kind of problem.

Thanks, Longman

If you fix the issue, kindly add following tag Reported-by: kernel test robot oliver.sang@intel.com

Details are as below: -------------------------------------------------------------------------------------------------->

To reproduce:
     git clone https://github.com/intel/lkp-tests.git
     cd lkp-tests
     sudo bin/lkp install job.yaml           # job file is attached in this email
     bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
     sudo bin/lkp run generated-yaml-file

     # if come across any failure that blocks the test,
     # please remove ~/.lkp and /lkp dir to run from a clean state.
