When we restrict to read/write/llseek for >2GB files (i.e., we won't
implement mmap() on them), the effect on speed will be probably
unnoticeable.

Yes, my comment was specifically directed at the design option of
allowing 64-bit offsets in the VM layer. No, I wasn't suggesting this
design option. Bypassing the VM layer is easier to implement, doesn't
impose a generic performance penalty for non-64-bit operations, and the
only shortcoming is the mmap limitation. I think it's the right
tradeoff.
