From 51d65049cd7e22a4d9ab8f2acb018a147f7f5146 Mon Sep 17 00:00:00 2001 From: Juntong Deng Date: Wed, 19 Mar 2025 14:53:48 -0700 Subject: bpf: Add struct_ops context information to struct bpf_prog_aux This patch adds struct_ops context information to struct bpf_prog_aux. This context information will be used in the kfunc filter. Currently the added context information includes struct_ops member offset and a pointer to struct bpf_struct_ops.
