From 00db12c3d141356a4d1e6b6f688e0d5ed3b1f757 Mon Sep 17 00:00:00 2001 From: Quentin Monnet Date: Fri, 9 Nov 2018 13:03:28 +0000 Subject: bpf: call verifier_prep from its callback in struct bpf_offload_dev In a way similar to the change previously brought to the verify_insn hook and to the finalize callback, switch to the newly added ops in struct bpf_prog_offload for calling the functions used to prepare driver verifiers. Since the dev_ops pointer in struct bpf_prog_offload is no longer used by any callback, we can now remove it from struct bpf_prog_offload.
