Subject: [PATCH 3/9] btrfs-progs: Makefile.extrawarn: Don't warn on sign compare
Date: Fri, 16 Nov 2018 15:54:20 +0800	[thread overview]
Message-ID: <20181116075426.4142-4-wqu@suse.com> (raw)
In-Reply-To: <20181116075426.4142-1-wqu@suse.com>

Under most case, we are just using 'int' for 'unsigned int', and doesn't
care about the sign.

The Wsign-compare is causing tons of false alerts.
Suppressing it would make W=1 less noisy.
