Solution:

https://android-review.googlesource.com/c/platform/external/f2fs-tools/+/683306 

 

With those 3 patches (first one was 

https://android-review.googlesource.com/c/platform/prebuilts/tools/+/682002 

for anyone who missed that), android-p-preview-2 builds and mostly 

works (tried on Nexus 6P with latest blobs from 

https://developers.google.com/android/blobs-preview ).
