Hi sin, attached are two patches for the -a flag on swapon and swapoff. there is room for improvement. and cleaning up, but i wasn't sure how you might want it organized. i altered the error handling a little bit, since it felt funny how you let the loop continue on error and possibly removing the EXIT_FAILURE return code if two devices are to be swapped on/off and the first failed but the second succeeds. I make it so that once EXIT_FAILURE is set it doesn't go away.
i don't update TODO. --Carlos
