Page-cache size limit at ia32 is now 4kB * 4G (16 TB).
Block-devices still have 0.5kB * 4G (2 TB - 1TB with sign)
maximum size limit, thus EXT2 volume cannot exceed 2TB,
possibly they cannot exceed 1TB..
There are many other things missing, than just syscalls,
but Linus has been distracted to play with a toy-project
of the week...

It depends on which glibc version they are compiled against.
If they are against glibc-2.0 (libc-6.0), then PERHAPS.
If they are against anything older, very likely *no*.
