What is being discussed her is not kfabrics. That is a totally different out of kernel pathfinding project at this point.
What is being discussed here is how to best solve the write/writev issue with the PSM interface. The code submitted was to move
to IOCTL instead, but people like Jason have suggested routing the IOCTLs through the verbs layer instead.
