Merge branch 'allow-bpf_map_sum_elem_count-for-all-program-types'
Anton Protopopov says:
====================
allow bpf_map_sum_elem_count for all program types
This series is a follow up to the recent change [1] which added
per-cpu insert/delete statistics for maps. The bpf_map_sum_elem_count
kfunc presented in the original series was only available to tracing
programs, so let's make it available to all.
The first patch makes types listed in the reg2btf_ids[] array to be
considered trusted by kfuncs.
The second patch allows to treat CONST_PTR_TO_MAP as trusted pointers from
kfunc's point of view by adding it to the reg2btf_ids[] array.
The third patch adds missing const to the map argument of the
bpf_map_sum_elem_count kfunc.
The fourth patch registers the bpf_map_sum_elem_count for all programs,
and patches selftests correspondingly.
