Subject: [PATCH 1/2] fix __set_page_dirty_no_writeback() return value
Date: Wed, 10 Nov 2010 17:00:27 +0800 [thread overview]
Message-ID: <1289379628-14044-1-git-send-email-lliubbo@gmail.com> (raw)
__set_page_dirty_no_writeback() should return true if it actually transitioned
the page from a clean to dirty state although it seems nobody used its return
value now.
