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

by Caleb Sander Mateos

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.
