Linus has pushed extremely hard for it, and it *is* his decision to
make.  If you want an authoritative answer I guess we need to wait until
Linus comes back.

I think it is downright looney to introduce a new ABI without a 64-bit
time_t at this point.

You are talking about a ktime_t; that is a kernel internal
implementation detail which can be changed later once the appropriate
kernel infrastructure is there, but we should make the change now to get
the external ABIs right, then we can microoptimize the kernel internal
implementation later.
