From 30465003ad776a922c32b2dac58db14f120f037e Mon Sep 17 00:00:00 2001 From: Dave Marchevsky Date: Sat, 17 Dec 2022 00:24:57 -0800 Subject: bpf: rename list_head -> graph_root in field info types Many of the structs recently added to track field info for linked-list head are useful as-is for rbtree root. So let's do a mechanical renaming of list_head-related types and fields: include/linux/bpf.h: struct btf_field_list_head -> struct btf_field_graph_root list_head -> graph_root in struct btf_field union kernel/bpf/btf.c: list_head -> graph_root in struct btf_field_info This is a nonfunctional change, functionality to actually use these fields for rbtree will be added in further patches.
