Subject: [patch 5/10] Allow ext3 pages to be written back by VM pressure
Date: Sun, 05 May 2002 13:56:06 -0700 [thread overview]
Message-ID: <3CD59C66.CADD24A9@zip.com.au> (raw)
When ext3 refiles journalled buffers for writeback, it is better to set the
page dirty as well as the buffer. So the page will be written out by
VM pressure rather than by kjournald alone.
