Subject: [PATCH v9 05/61] Export __set_page_dirty
Date: Tue, 13 Mar 2018 06:25:43 -0700 [thread overview]
Message-ID: <20180313132639.17387-6-willy@infradead.org> (raw)
In-Reply-To: <20180313132639.17387-1-willy@infradead.org>
From: Matthew Wilcox <mawilcox@microsoft.com>
XFS currently contains a copy-and-paste of __set_page_dirty(). Export
it from buffer.c instead.
Signed-off-by: Matthew Wilcox <mawilcox@microsoft.com>
