The patch titled
swsusp: fix sysfs interface
has been removed from the -mm tree. Its filename was
swsusp-fix-sysfs-interface.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: swsusp: fix sysfs interface
From: Rafael J. Wysocki <[EMAIL PROTECTED]>
The sysfs files /sys/power/disk and /sys/power/state do not work as
documented, since they allow the user to write only a few initial
characters of the input string to trigger the option (eg. 'echo pl >
/sys/power/disk' activates the platform mode of hibernation). Fix it.
Special thanks to Peter Moulder <[EMAIL PROTECTED]> for
pointing out the problem.
