Then somebody do the analysis.  And please an analysis which takes into=
=20
account that some programs might need to be adapted to take advantage o=
f=20
d_type or non-optional data from the proposed statlite.

Plus, how often are these commands really used on such filesystems?  I'=
d=20
hope that chown -R or so is a once in a lifetime thing on such=20
filesystems and not worth optimizing for.

I'd suggest until such data is provided the readdirplus plans are put o=
n=20
hold.  statlite I have no problems with if the semantics is changed as =
I=20
explained.
