Thanks a lot for your work on this, Xiubo (and Jeff!).  I assume this set
is what's on the 'testing' branch.  I've done some testing on that branch
recently, but I'll start having another look at v16 and run some more
tests.

Am I right assuming that this v16 patchset means we are NOT getting this
merged into 6.3?

Cheers,
