That was wishful thinking - after 1500 x 5 runs there are 2 failures also on the backport branch. It is still better than 4 failures out of 800 x 5 runs on baseline, but I can not call that a proof for bug fix - only no regression. > > > > > > If these results don't change, I would be happy to get an ACK for the > > > series so I can post it after the long soaking. > > > > Patches 4-9 are an easy > > Acked-by: Darrick J.

I'll keep it spinning. Thanks, Amir.
