Date: Thu, 7 May 2009 00:39:15 +1000 From: Nigel Cunningham <nigel@...onice.net> To: linux-pm@...ts.linux-foundation.org, linux-kernel@...r.kernel.org, tuxonice-devel@...ts.tuxonice.net Cc: Nigel Cunningham <nigel@...onice.net> Subject: [PATCH 19/19] TuxOnIce: Don't try to wake kswapd if the freezer is on. If a process gets into wakeup_kswapd while other processes are frozen, we don't want it to actually wake kswapd (memory pressure may be caused by TuxOnIce trying to free memory).
