Subject: [PATCH AUTOSEL 4.14 57/60] mm/gup.c: mark undo_dev_pagemap as __maybe_unused
Date: Fri, 19 Jul 2019 00:11:06 -0400 [thread overview]
Message-ID: <20190719041109.18262-57-sashal@kernel.org> (raw)
In-Reply-To: <20190719041109.18262-1-sashal@kernel.org>
From: Guenter Roeck <linux@roeck-us.net>
[ Upstream commit 790c73690c2bbecb3f6f8becbdb11ddc9bcff8cc ]
Several mips builds generate the following build warning.
mm/gup.c:1788:13: warning: 'undo_dev_pagemap' defined but not used
The function is declared unconditionally but only called from behind
various ifdefs. Mark it __maybe_unused.
