Subject: [PATCH 0/5] autogroup runtime enable/disable tuning fix

This patchset focus on autogroup runtime enable/disable tuning
issue.

Below is my test when disable autogroup at runtime:

vanilla:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
 1046 test1     20   0 25544  844  276 R 50.0  0.0   0:23.30 bash               
 1044 test2     20   0 25544  860  280 R 25.2  0.0   0:20.55 bash               
 1045 test2     20   0 25544  864  284 R 24.8  0.0   0:17.48 bash

patched:
  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
  991 test1     20   0 25544  844  276 R 31.7  0.0   2:05.93 bash               
  992 test2     20   0 25544  848  276 R 31.7  0.0   1:16.84 bash               
  994 test2     20   0 25544  856  284 R 29.8  0.0   1:02.67 bash

Yong Zhang (5):
      sched, autogroup, sysctl: use proc_dointvec_minmax instead.
      sched: hide cfs_rq of autogroup if autogroup is disabled
      sched, autogroup: stop going ahead if autogroup is disabled
      sched: refactor task_group()
      sched, autogroup: runtime enable/disable tuning fix
