[PATCH 0/5] bpf: use const pointer for struct_ops cfi_stubs

struct bpf_struct_ops's cfi_stubs field is used as a readonly pointer
but has type void *. Change its type to void const * to allow it to
point to readonly global memory. Update the struct_ops implementations
to declare their cfi_stubs global variables as const.

Caleb Sander Mateos (5):
bpf: use const pointer for struct_ops cfi_stubs
HID: bpf: make __bpf_hid_bpf_ops const
sched_ext: make __bpf_ops_sched_ext_ops const
net: make cfi_stubs globals const
selftests/bpf: make cfi_stubs globals const
