This one is based on a new api: flush/invalidate_kernel_vmap_range() making it clear that the fs/driver is the entity managing the vmaps ... it also drops the block inputs because coherency management is now the responsibility of the user. The xfs interface is nicely simplified with this approach. Could someone check this on arm and sh?
