| From | Nigel Cunningham <> | Subject | [PATCH 19/19] TuxOnIce: Don't try to wake kswapd if the freezer is on. | Date | Thu, 7 May 2009 00:39:15 +1000 |
| |
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).
