Ah that was meant to be a fixlet - so that on top of the original "zswap: make shrinking memcg-aware" patch. The intention was to eventually squash it...
But this is getting a bit annoyingly confusing, I admit. I just rebased to mm-unstable + squashed it all again, then sent one single replacement patch:
[PATCH v5 3/6 REPLACE] zswap: make shrinking memcg-aware
Thank you for the quick response.
Yes, I am able to download your replacement version of patch 3. Just FYI, I am using "git mailsplit" to split up the mbox into 6 separate patch files. On mm-unstable, I am able to apply your replacement patch 3 cleanly. I also need some help on the patch 0005, it does not apply cleanly either.

Let me know if this still fails to apply. If not, I'll send the whole thing again as v6! My sincerest apologies for the troubles and confusion :(
No problem at all. Thanks for your help on patch 3.

Hmm my guess is that I probably sent this out based on an outdated mm-unstable. There has since been a new zswap selftest merged to mm-unstable (written by no other than myself - oh the irony), so maybe it does not apply cleanly anymore with git am.
I was, however, able to apply the patch with the -3 argument, i.e:
git am -3 ../mbox/0005
This will fall back to the 3-way merge if direct application fails. And, FWIW, the kselftest still seems to build.
I think you'll have to do the same with the 6th patch as well. My guess is that on my latest rebase attempt, this was done silent and automatically, so I did not notice this.
Let me know if this works. Worst case scenario, I can still rebase 'n resend the patch series :)
