Hi, I have just stmbled over 16db3d3f1170 ("kernel/sysctl.c: threads-max observe limits") and I am really wondering what is the motivation behind the patch. We've had a customer noticing the threads_max autoscaling differences btween 3.12 and 4.4 kernels and wanted to override the auto tuning from the userspace, just to find out that this is not possible.
Why do we override user admin like that? I find it quite dubious to be honest. Especially when the auto-tunning is just a very rough estimation and it seems quite arbitrary. Thanks -- Michal Hocko SUSE Labs
