Subject: [PATCH AUTOSEL 4.14 17/17] gcov: Disable gcov build with GCC 10
Date: Mon, 7 Sep 2020 12:35:00 -0400 [thread overview]
Message-ID: <20200907163500.1281543-17-sashal@kernel.org> (raw)
In-Reply-To: <20200907163500.1281543-1-sashal@kernel.org>
From: Leon Romanovsky <leonro@nvidia.com>
[ Upstream commit cfc905f158eaa099d6258031614d11869e7ef71c ]
GCOV built with GCC 10 doesn't initialize n_function variable. This
produces different kernel panics as was seen by Colin in Ubuntu and me
in FC 32.
As a workaround, let's disable GCOV build for broken GCC 10 version.
