Merge branch 'bpf-prog-map-ID'
Martin KaFai Lau says:
====================
Introduce bpf ID
This patch series:
1) Introduce ID for both bpf_prog and bpf_map.
2) Add bpf commands to iterate the prog IDs and map
IDs of the system.
3) Add bpf commands to get a prog/map fd from an ID
4) Add bpf command to get prog/map info from a fd.
The prog/map info is a jump start in this patchset
and it is not meant to be a complete list. They can
be extended in the future patches.
v3:
- I suspect v2 may not have applied cleanly.
In particular, patch 1 has conflict with a recent
change in struct bpf_prog_aux introduced at a similar time frame:
8726679a0fa3 ("bpf: teach verifier to track stack depth")
v3 should have fixed it.
v2:
Compiler warning fixes:
- Remove lockdep_is_held() usage. Add comment
to explain the lock situation instead.
- Add static for idr related variables
- Add __user to the uattr param in bpf_prog_get_info_by_fd()
and bpf_map_get_info_by_fd().
