[libvirt] [PATCH 00/19] implement cgroups v2 devices support



In cgroups v2 there is no devices controller, BPF should be used
instead.

Patches 3 - 12 will be squashed into single commit and they need to be
compiled together, I've separated them to make review easier.

Pavel Hrdina (19):
  util: introduce virbpf helpers
  vircgroup: introduce virCgroupV2DevicesAvailable
  vircgroup: introduce virCgroupV2DeviceLoadProg
  vircgroup: introduce virCgroupV2DeviceAttachProg
  vircgroup: introduce virCgroupV2DeviceDetectProg
  vircgroup: introduce virCgroupV2DeviceCreateProg
  vircgroup: introduce virCgroupV2DeviceReallocMap
  vircgroup: introduce virCgroupV2DevicePrepareProg
  vircgroup: introduce virCgroupV2DeviceRemoveProg
  vircgroup: introduce virCgroupV2DeviceGetPerms
  vircgroup: introduce virCgroupV2DeviceGetKey
  vircgroup: introduce virCgroupV2AllowDevice
  vircgroup: introduce virCgroupV2DenyDevice
  vircgroup: introduce virCgroupV2AllowAllDevices
  vircgroup: introduce virCgroupV2DenyAllDevices
  vircgroup: workaround devices in hybrid mode
  vircgroupv2: detech BPF program before removing cgroup
  vircgroupv2: use dummy process to workaround kernel bug with systemd
  vircgroupmock: mock virBPFQueryProg
