[PATCH] swpsuspend: Have suspend to disk use factors of sys_reboot
Eric W. Biederman [Tue, 26 Jul 2005 18:01:17 +0000 (12:01 -0600)]
The suspend to disk code was a poor copy of the code in
sys_reboot now that we have kernel_power_off, kernel_restart
and kernel_halt use them instead of poorly duplicating them inline.
