Feng Yang says:
====================
bpf: Allow some trace helpers for all prog types
From: Feng Yang <yangfeng@kylinos.cn>
This series allow some trace helpers for all prog types.
if it works under NMI and doesn't use any context-dependent things,
should be fine for any program type. The detailed discussion is in [1].

Changes in v3:
- cgroup_current_func_proto clean.
- bpf_scx_get_func_proto clean. Thanks, Andrii Nakryiko.
- Link to v2: https://lore.kernel.org/all/20250427063821.207263-1-yangfeng59949@163.com/
Changes in v2:
- not expose compat probe read APIs to more program types.
- Remove the prog->sleepable check added for copy_from_user,
- or the summarization_freplace/might_sleep_with_might_sleep test will fail with the error "program of this type cannot use helper bpf_copy_from_user"
- Link to v1: https://lore.kernel.org/all/20250425080032.327477-1-yangfeng59949@163.com/
