Merge branch 'bpf-retire-the-unsupported_ops-usage-in-struct_ops'
Martin KaFai Lau says:
====================
bpf: Retire the unsupported_ops usage in struct_ops
From: Martin KaFai Lau <martin.lau@kernel.org>
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.
