This only affects the Linux kernel as shipped with Red Hat Enterprise

NFSv4 mount. This patch fixed the problem, although we only backported
the relevant parts of the patch,


Assuming that the fix for this one is correct and sufficient (and it
appears to be), this is definitely no worse than a DoS. :-)
