New Revision: 229956
URL: http://svn.freebsd.org/changeset/base/229956

Log:
  jwd@ reported via email that the "CacheSize" field reported by "nfsstat -e -s"
  would go negative after using the "-z" option to zero out the stats.
  This patch fixes that by not zeroing out the srvcache_size field
  for "-z", since it is the size of the cache and not a counter.
  
  MFC after:	2 weeks
