>Description:
I wanted to learn how KLDs work, and in the process, I KLD-ified
EXT2FS support. Below is a patch to sys/modules. I am not entirely
certain I have done this correctly, but with it loaded, I have been
able to read and write to a file formatted using mke2fs from Linux.
While I was at it, I "fixed" modules/Makefile so that each sub-
directory lies on a seperate line, as in most of the other Makefiles.
