From 2145297ac316df0211f0509d6e3cc913f30332bf Mon Sep 17 00:00:00 2001 From: Alexander Popov Date: Wed, 24 Jun 2020 15:33:26 +0300 Subject: [PATCH] gcc-plugins/stackleak: Don't instrument itself [ Upstream commit 005e696df65d0ff90468ecf38a50aa584dc82421 ] There is no need to try instrumenting functions in kernel/stackleak.c. Otherwise that can cause issues if the cleanup pass of stackleak gcc plugin is disabled.
