[PATCH v2 0/2] tools/bpf/bpftool: Fix vmlinux BTF state cleanup

[Yichong Chen]

This series fixes stale vmlinux BTF state in bpftool batch mode.

Patch 1 resets the map command cached vmlinux BTF pointer when the
command releases it, and avoids freeing the cached object from the
map lookup path.

Patch 2 resets the struct_ops command cached vmlinux BTF pointer and
dependent cached map info state after each struct_ops command.

Changes in v2:
- Fold the map lookup path fix into patch 1.
- Update patch 1 subject and commit message to cover map commands
  rather than only map dump.
