I don't think such a patch, involving the kernel, a userland daemon and
changes into glibc, should be integrated into Debian if it has not been
integrated upstream. I believe such things should be standardized a
minimum, so that all distributions share the same implementation.
Please submit this patch upstream (http://sources.redhat.com/bugzilla/)
and when it has been merged, we will backport changes from CVS.
