The furor was caused by concerns Al Viro expressed about
locking/deadlock issues that reiser4 introduced.  

The bigger issue with xattr support is two-fold.  First of all, there
are the progams that are expecting the existing extended attribute
interface, and not implementing it will simply mean that as far as
Samba, and other applications, Reiser4 simply will not haved xattr
support.

More importantly are the system-level extended attributes, such as
those used by SELINUX, which by definition are not supposed to be
visible to the user at all, but only are supposed to be there for the
SELINUX (or some other kernel layer, in general) to access.   

Not supporting xattrs means that those distro's that use SELINUX by
default (i.e., RHEL, Fedora, etc.) won't want to use reiser4, because
SELINUX won't work on reiser4 filesytstems.

Whether or not Hans cares about this is up to him....
