Note we are speaking of 2 lines of code.

But the old versions (the one shipped on Mdk) didn't work for online resizing (this was verified by me with lots of warnings and a Oops on reiserfs code); in fact, this ability is so new that is not even documented in manpages. -- Paolo Giarrusso, aka Blaisorblade Linux registered user n. 292729 http://www.user-mode-linux.org/~blaisorblade
