====================
bpf: Retire the unsupported_ops usage in struct_ops

From: Martin KaFai Lau <[email protected]>

This series retires the unsupported_ops usage and depends on the
null-ness check on the cfi_stubs instead.

Please see individual patches for details.

v2:
- Fixed a gcc compiler warning on Patch 1.
