i agree.  i haven't done timings yet, all the units i could do them on
are on a runin suspend resume test.  also, i don't see the advantage to
doing the resize in initramfs, because that would delay booting.  i
think it should be done with the system up and running.  i gather it is
an interruptible process.  daniel notes in #10040 that he will
investigate how safe ext4 online resize is.
