- * Pavel Machek <pavel@....cz>:
- * Modifications, defectiveness pointing, being with me at the very beginning,
- * suspend to swap space, stop all tasks. Port to 2.4.18-ac and 2.5.17.
- *
- * Steve Doddi <dirk@...h.demon.co.uk>:
- * Support the possibility of hardware state restoring.
- *
- * Raph <grey.havens@...thling.net>:
- * Support for preserving states of network devices and virtual console
- * (including X and svgatextmode)
- *
- * Kurt Garloff <garloff@...e.de>:
- * Straightened the critical function in order to prevent compilers from
- * playing tricks with local variables.
- *
- * Andreas Mohr <a.mohr@...lto.de>
- *
- * Alex Badea <vampire@...ro>:
- * Fixed runaway init
- *
- * Rafael J. Wysocki <rjw@...k.pl>
- * Reworked the freeing of memory and the handling of swap
- *
- * More state savers are welcome. Especially for the scsi layer...
- *
- * For TODOs,FIXMEs also look in Documentation/power/swsusp.txt
