Indeed, for a very large directory you might get some speedup using
samples/ilm/mmfind directory -ls -maxdepth 1
There are some caveats, the same as those for the command upon which
mmfind rests, mmapplypolicy.

Interesting, thanks for the information Marc. Could there be an
improvement
for something like "ls -l some-dir" using the API, though? Instead of
getdents +
stat for every file (entering and leaving kernel mode many times), could
it be done
in one operation with one context switch?
