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.

$ git mailsplit -ozswap-pool-lru

$ git am patches/zswap-pool-lru/0001

When you have resolved this problem, run "git am --continue".
If you prefer to skip this patch, run "git am --skip" instead.
To restore the original branch and stop patching, run "git am --abort".

No problem at all. Thanks for your help on patch 3.
