Why bother?  Generally /tmp is erased on a reboot, so there's no point
using a journal for it at all.  In fact, I normally mount /tmp using
tmpfs, so that /tmp is stored in memory and automatically disappears
when I reboot my laptop.....  (This is especially true if you're using
a distro which wipes /tmp on reboot by default, but even if you don't,
in my experience if you assume that nothing in /tmp gets preserved
across a reboot, it's much easier to keep /tmp clean.)
