Then somebody do the analysis. And please an analysis which takes into
account that some programs might need to be adapted to take advantage of
d_type or non-optional data from the proposed statlite.
Plus, how often are these commands really used on such filesystems? I'd
hope that chown -R or so is a once in a lifetime thing on such
filesystems and not worth optimizing for.
I'd suggest until such data is provided the readdirplus plans are put on
hold. statlite I have no problems with if the semantics is changed as I
explained.
