using lseek() on large files

[James Rich <james@xxxxxxxxxxxxx>]

Is it correct the xfs supports file sizes larger than can be addressed by
lseek()?  lseek() uses a long as the offset, which on my system is 32
bits.  If it is correct that XFS supports such large file sizes, how are
the file contents accessed?  And does the kernel syscall allow larger
offsets?
