Hi all,
In the commit
deb7aa308ea26 cpuset: reorganize CPU / memory hotplug handling
It states so in the comment for this function:
/*
...
* Note that CPU offlining during suspend is ignored. We don't modify
* cpusets across suspend/resume cycles at all.
*/
However, I did see the function cpuset_hotplug_workfn called in the resume
path, which costs 10+ ms on our platform. I was wondering if the statement
is still true, could this function be bypassed in the resume path?
I also filed a bug for this.
https://bugzilla.kernel.org/show_bug.cgi?id=216321
I wish to be personally CC'ed.
Thanks,
Rick
