Subject: [PATCH]  - Disable code which allows getnewvnode() to fail.  Many
 ffs_vget() callers    do not correctly deal with failures.  This presently
 risks deadlock    problems if dependency processing is held up by failures to
 allocate    a vnode, however, this is better than the situation with the
 failures.
