[Devel] [PATCH rh7 0/2] fairsched stats

[Vladimir Davydov]

Currently, cpu stats are broken for UUID-named CTs. First, reading
/proc/stat from inside a container or /proc/vz/vestat on the host fails
with ENOENT if there is a UUID-named CT. Patch 1 fixes that. Second,
there is no new interface for getting loadavg for UUID-named CTs, which
would be a successor of the legacy VZCTL_GET_CPU_STAT ioctl. Patch 2
adds cpu.proc.loadavg that mimics behavior of /proc/loadavg.

  farisched: switch methods showing stats from numeric id to name
  fairsched: add cpu.proc.loadavg to the cpu cgroup
