BPF cleanups and misc updates

This patch set adds couple of cleanups in first few patches, exposes owner_prog_type for array maps as well as mlocked mem for maps in fdinfo, allows for mount permissions in fs and fixes various outstanding issues in selftests and samples.

Thanks!

Daniel Borkmann (6):
bpf: drop unnecessary context cast from BPF_PROG_RUN
bpf: drop useless bpf_fd member from cls/act
bpf: reuse dev_is_mac_header_xmit for redirect
bpf: add owner_prog_type and accounted mem to array map's fdinfo
bpf: allow for mount options to specify permissions
bpf: fix multiple issues in selftest suite and samples
