Raghu Vatsavayi says:

====================
liquidio VF data path

Following is V3 patch series that adds support for VF
data path related features. It also has following changes
related to previous comments:
1) Remove unnecessary "void *" casting.
2) Remove inline for functions and let gcc decide.

Please apply patches in following order as some of them
depend on earlier patches.
