    sys/sys              namecache.h 
  Log:
  Fix a vnode recyclement namecache<->vnode deadlock introduced with recent
  changes.  Two primary fixes have been made to the allocvnode and vnlru
  recyclement code.
  
  There are still a few possible deadlocks in less traveled code
  paths (such as in procfs) that existed prior to recent changes.
