[PATCH] Update tags to record who made them
And finally what all of this has been leading up to. The 2 line code change to record who made a tag, and the 8 line code change to check that we recorded the tag. Gosh the error checking is always so much bigger than the code :) Signed-off-by: Linus Torvalds <torvalds@osdl.org>
