First patch tries to remove kzalloc/kfree from getsockopt for the
common cases.

Second patch switches cgroup_bpf_enabled to be per-attach to
to add only overhead for the cgroup attach types used on the system.

No visible user-side changes.

Stanislav Fomichev (2):
  bpf: try to avoid kzalloc in cgroup/{s,g}etsockopt
  bpf: split cgroup_bpf_enabled per attach type
