SVN rev 212562 on 2010-09-13 17:18:49Z by mdf
MFC r209053:
Add INVARIANTS checking that numfreebufs values are sane. Also add a
per-buf flag to catch if a buf is double-counted in the free count.
This code was useful to debug an instance where a local patch at Isilon
was incorrectly managing numfreebufs for a new buf state.
