2G file size limitation question

this message is not about development, but rather customization of the
kernel.

as far as i can tell, the ext2 filesystem code limits files to a maximum
of 2G (although i haven't yet found _exactly_ where this limit is set...).

we have a need to use files larger than 2G (ugh, dont ask - we also need
to bump our machine up from 512M to 1G or more of memory...), so i have a
couple of questions:

- why is there a 2G limit?
- can the 2G limit be _safely_ increased (to, say, about 5G)?
- if so, what changes are needed in the ext2 code to do it?

the machine in question is running a pre-something version of 2.0.31. i
wouldn't mind moving to a newer 2.0.x kernel, if need be.

thanks a lot.
