From a396eda5517ac958fb4eb7358f4708eb829058c4 Mon Sep 17 00:00:00 2001 From: Daniel Xu Date: Mon, 23 Aug 2021 19:43:48 -0700 Subject: bpf: Extend bpf_base_func_proto helpers with bpf_get_current_task_btf() bpf_get_current_task() is already supported so it's natural to also include the _btf() variant for btf-powered helpers. This is required for non-tracing progs to use bpf_task_pt_regs() in the next commit.
