Subject: [PATCH] Add freezer call in
Date: Wed, 16 Mar 2005 09:21:20 +1100 [thread overview]
Message-ID: <1110925280.6454.143.camel@desktop.cunningham.myip.net.au> (raw)
This patch adds a freezer call to the slow path in __alloc_pages. It
thus avoids freezing failures in low memory situations. Like the other
patches, it has been in Suspend2 for longer than I can remember.
