Some concern was expressed over the lguest review status, so I shall send the patches out again for people to review, to test, to make observations about the author's personal appearance, etc. I'll plan on sending these patches off to Linus in a week's time, assuming all goes well. Thanks. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body
