    sys/kern             vfs_subr.c 
  Log:
  Detect that a vnode has been reclaimed while vflush() was waiting to lock
  the vnode and restart the loop.  Vflush() is vulnerable since it does not
  hold a reference to the vnode and it holds no other locks while waiting
  for the vnode lock.  The vnode will no longer be on the list when the
  loop is restarted.
