Issues is only partially fixed. On running the redis benchmark I see the following errors:

[74101.316081] BUG: Bad rss-counter state mm:ffff8800cc773c00 idx:1 val:1
[74377.596209] BUG: Bad rss-counter state mm:ffff8802740192c0 idx:1 val:528
[74377.601514] BUG: non-zero nr_ptes on freeing mm: 1
[74377.603660] BUG: non-zero nr_pmds on freeing mm: 1

The benchmark completes successfully despite the errors.
