Except for the fifth patch in this series which was found in an internal testing. The Sashiko review on DTHEv2 hashing driver patch series v5 pointed out some pre-existing issues which needed to be fixed [1]. One of the issues had already been flagged by kernel test bot and a fix sent on the list by Mert [2]. I included this patch in this series with minor edits. Then the Sashiko review page for [2] had more comments [3] Overall this resulted in a bunch of fixes patches which would have deviated the DTHEv2 hashing driver series had they been included with it. So I clubbed them together in a new patch series which is this.
