Another poster stated that on ext3,
directories can grow, but not shrink.

If /tmp is its entire partition, I think that the only way
is to reformat the partition.
You don't necessarily have to reboot, but you will need to kick off
anyone using /tmp .
If /tmp is a soft link to /fred/tmp and /fred is its entire partition,
you might be able to do something like this.
# cd /fred
# mkdir new.tmp
# cd new.tmp
# ln ../tmp/* . # hard links won't work on directories
# cd ..
# mv tmp old.tmp
# # 'twould be best if no one tried to use /tmp at this point
# mv new.tmp tmp
# rm -r old.tmp
There might still be problems if someone had the
original /tmp as the current directory or just open.
