  SVN rev 181119 on 2008-08-01 09:46:19Z by kib
  
  MFC r178243:
  Move the head of byte-level advisory lock list from the
  filesystem-specific vnode data to the struct vnode. Provide the
  default implementation for the vop_advlock and vop_advlockasync.
  Purge the locks on the vnode reclaim by using the lf_purgelocks().
  The default implementation is augmented for the nfs and smbfs.
  In the nfs_advlock, push the Giant inside the nfs_dolock.
  
  Before the change, the vop_advlock and vop_advlockasync have taken the
  unlocked vnode and dereferenced the fs-private inode data, racing with
  with the vnode reclamation due to forced unmount. Now, the vop_getattr
  under the shared vnode lock is used to obtain the inode size, and
  later, in the lf_advlockasync, after locking the vnode interlock, the
  VI_DOOMED flag is checked to prevent an operation on the doomed vnode.
  
  MFC r178247:
  Fix compilation with LOCKF_DEBUG.
  
  As was announced on the stable@, the MFC changes the VFS KBI on RELENG_7.
