Not an issue with this commit. I just noticed that
commit f2e10bff16a0 ("bpf: Add support for BPF_OBJ_GET_INFO_BY_FD for bpf_link")
added MAX_BPF_LINK_TYPE to enum bpf_link_type.
While this commit is correctly adding __MAX_BPF_CMD that
is consistent with old __MAX_BPF_ATTACH_TYPE (added in 2016)
and __MAX_BPF_REG (added in 2014).
I think it would be good to follow up with adding two underscores
to MAX_BPF_LINK_TYPE just to keep things consistent in bpf.h.
