Have you tried the obvious?
1. mkdir tmpdir
2. mv everything from olddir/* to tmpdir, [*]
3. rmdir olddir
4. mv tmpdir olddir
[*] "mv olddir/* tempdir" may not work if you have many files left.
Use a script, find(1), tar(1) or whatever you feel comfortable
with, instead.
The directory could be in theory compacted, but only if it is not
in use (i.e. not mapped in the kernel's VNODE(9)s). It's perhaps
too cumbersome to create a syscall that would do this.
