Re: 1GB Limit on EXT2FS?

I recently saw an ext2fs update from Remy (or was it Ted?) that expanded
ext2fs max file size using the methods that have long been discussed here.
I wouldn't be surprised to see that update in 2.1.x and thus in 2.2.

According to Khimenko Victor:

Look again: There is already an llseek call, and the kernel keeps
track of current position with a "long long".

There are memory mapping issues when exceeding 2G, but that's a
separate issue.
