It looks like there are a number of problems, but the one reported
above is the only one that gets 'hit'. The NFS code pretty much
ignores the VOP semantics for freeing path name elements but it
just happens to get called with the path name (cnp) structure flagged
the way it happens to decide to use it, so it works. But there is
probably some leakage of NAMEI nodes when NFS errors occur.
I've only committed the fix for the vrele panic to -3.x. The fix
to the rest of the mis-used path elements has been committed to -4.x
and will not be backported to -3.x until after the release since
I'm not 100% sure those other fixes are correct. -3.x should not be
detrimentally effected by not having the other junk in.
Confused yet? :-)
