        If I remember correctly, on linux x86, i.e. 32-bit linux, the VFS layer
is still 32 bit. this means that no matter XFS's or reisers limits, you are
limited to 2gb for files. Redhat has released a fix to increase that limit
to 4 or 8gb, I *think* in their "professional" kernels or whatever.  I also
believe that SGI's development team is working with kernel developers for a
workaround so we can have a 64-bit VFS layer, thus truely being able to
exploit XFS's (and other fs's) ability.  I have heard from friends (very
smart friends with nice boxes) that even old ext2's limit is not 2gb, that
it's a VFS thing. they claim that on a 64-bit arch. they can exceed the 2gb
file size limit no problem. Ponder that. :)
