  Log:
  Add some diagnostic messages to try to catch a ufs_dirbad panic before it
  happens.
  
  MFC: Reorder BUF_UNLOCK() - it must occur after b_flags is modified, not
  before.
  
  A newly created non-VMIO buffer is now marked B_INVAL.  Callers of getblk()
  now always clear B_INVAL before issuing a READ I/O or when clearing or
  overwriting the buffer.  Before this change, a getblk() (getnewbuf),
  brelse(), getblk() sequence on a non-VMIO buffer would result in a buffer
  with B_CACHE set yet containing uninitialized data.
  
  MFC: B_NOCACHE cannot be set on a clean VMIO-backed buffer as this will
  destroy the VM backing store, which might be dirty.
  
  MFC: Reorder vnode_pager_setsize() calls to close a race condition.
