Agreed.  Mel's patch basically restores the previous behavior while
keeping the 64-bit timestamp size.

Considering where we are at with the merge window, I'm going to merge
this into the audit/next branch and not send this up to Linus during
the current window; while the patch is small, I like to give things
some time in linux-next before sending them up.
