Hello, Zhangjin,

My pull request only contains those commits that Thomas and Willy deemed
ready for the v6.7 merge window, which should open in a few days.  So it
might be that you series is in Willy's repo, and will be in the set to
be sent for the v6.8 merge window.

But I must defer to Willy and Thomas.

							Thanx, Paul
