These three patches are about PSI.
patch 1: Fixed PSI statistics error caused by unzeroed memory
in struct psi_group.
patch 2 and patch 3 are to clean up some unused functions
and parameters.

Hao Jia (3):
  sched/psi: Zero the memory of struct psi_group
  sched/psi: Remove unused parameter nbytes of psi_trigger_create()
  sched/psi: Remove redundant cgroup_psi() when !CONFIG_CGROUPS
