Subjectthreads-max observe limits
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.
