We have a vfs_dirsort module that sorts alphabetically,
but it would be hard to sort by date as the underlying
POSIX interface that gets directory entries, readdir()
only returns the name and not the meta-data such as
timestamps.

You'd have to make a new module based on dirsort
that does a stat after we get the name from readdir
and then uses that meta data as input to the qsort
compare function.
