Re: linux emulation: listxattr

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

Thanks for looking into this.

EF> Does anyone feel like adding a (maybe dummy) implementation for it?
I've found a workaround: setting "skipacl yes" and "skipaclupdatecheck yes"
in dsm.opt helps. You don't easily find that in the TSM documentation
because it always speaks of "extended attributes"---only that command's
description doesn't, but says "ACL".

CZ> It returns EOPNOTSUP currently, isn't that enough?
I'm confused as to what it returns. Looks like it returns 38 (or -38?);
in Penguinish, that would be ENOSYS; however, kdump says ,,too many processes''.

CZ> Do you have a ktrace of it?
