Subject: [08/25] kbuild: Disable -Wunused-but-set-variable for gcc 4.6.0
Date: Tue, 22 Nov 2011 16:20:58 -0800 [thread overview]
Message-ID: <20111123002207.735751460@clark.kroah.org> (raw)
In-Reply-To: <20111123002222.GA2376@kroah.com>
2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------
Content-Length: 983
Lines: 33
From: Dave Jones <davej@redhat.com>
commit af0e5d565d2fffcd97d1e2d89669d627cc04e8b8 upstream.
Disable the new -Wunused-but-set-variable that was added in gcc 4.6.0
It produces more false positives than useful warnings.
This can still be enabled using W=1
[gregkh - No it can not for 2.6.32, but we don't care]
