  Modified files:
    sys/nfsclient        nfs_bio.c nfs_vnops.c 
  Log:
  This change grabs the vnode lock for NFS client vnodes when calling
  VOP_SETATTR() or VOP_GETATTR(); without these locks (a) VFS_DEBUG_LOCKS
  will panic, and (b) it may be possible to corrupt entries in the cached
  vnode attributes in the nfsnode, since nfsnode attribute cache data is
  also protected by the vnode lock.
