Revision 436b0f76f2cee6617f27a649637766628909dd5d authored by Linus Torvalds on 04 December 2005, 05:10:42 UTC, committed by Linus Torvalds on 04 December 2005, 05:10:42 UTC
Hey, for no other reason than the fact that I'll be off-line for a week. Of course, I could force everybody to just use git (and when I'm emperor of the world, don't think I won't!), but it seems some people want to just test official releases. Even if they are just -rc's. By the time I'm back, Andrew will have fixed all my bugs, and I'll release it as 2.6.15 and take all the credit. Mwahahahaaa Signed-off-by: Linus Torvalds <torvalds@osdl.org>
