Just doesn't seem logical to have CONFIG_SWAP ifdef cover the whole thing, regardless that it produces the desired result. I'm going to submit a fixup patch to Linus covering all this stuff, after making a more comprehensive test case (yes I actually did test this patch with a few different cases before submitting it, so I must have been unlucky with uninitialised data). If he wants to apply it rather than back out the patch entirely, its up to him. I don't think there is any reason to panic. I did completely forget the result vector, but AFAIKS that's the only real bug in it. -- SUSE Labs, Novell Inc.
