Pu Lehui d1a426171d bpf: Use precise image size for struct_ops trampoline ... For trampoline using bpf_prog_pack, we need to generate a rw_image buffer with size of (image_end - image). For regular trampoline, we use the precise image size generated by arch_bpf_trampoline_size to allocate rw_image. But for struct_ops trampoline, we allocate rw_image directly using close to PAGE_SIZE size. We do not need to allocate for that much, as the patch size is usually much smaller than PAGE_SIZE. Let's use precise image size for it too.
