[Devel] [PATCH VZ10 0/3] bpf/devcg: add interface for dumping programs

[Pavel Tikhomirov]

We've allowed bpf device cgroup programs in Containers in previous
patches, now let's give CRIU and intercace to be able to dump them,
so that Virtuozzo Containers with such programs can be migrated.

Feature: BPF checkpoint/restore

  bpf: report original insns of cgroup device programs
  selftests/ve_devcg_bpf: factor device program insns into
    DEVCG_PROG_INSNS
  selftests/ve_devcg_bpf: test orig_insns reporting via
    BPF_OBJ_GET_INFO_BY_FD
