From ba8bd24bbb6cef9f4d22ff8884b9995bddb70d56 Mon Sep 17 00:00:00 2001 From: Martin Kelly Date: Thu, 10 Oct 2024 12:33:01 -0700 Subject: [PATCH] bpf: Update bpf_override_return() comment The documentation says CONFIG_FUNCTION_ERROR_INJECTION is supported only on x86. This was presumably true at the time of writing, but it's now supported on many other architectures too. Drop this statement, since it's not correct anymore and it fits better in other documentation anyway.
