[Tux3] [PATCH 2/2] Implementing listattr for fuse: implementation of tux3_listxattr

[Jonas Fietz]

Hi,

second part of my patch. As the note says, this is untested for multiple
xattrs.
Hirofumi and I just noticed another problem with the xattrs, so the last
patch may be faulty. So please don't apply that yet as further research
is needed.

Implementation  of tux3_listxattr.
Quite simple, as it only has to patch through to xattr_list. This is still
untested for multiple xattrs as there are further problems with those
