Ok, thanks for the heads up. For the get_user_pages() patches that build on these fixes I'm assuming your review bandwidth is in short supply to also give an XFS sign-off on those changes for 4.4?
I'm wondering if we can take a conservative step forward with those patches for 4.4. if XFS and EXT4 interactions need more time to get worked out, which I believe they do, I can conceive just turning on get_user_pages() support for DAX-mappings of the raw block device. This would be via the new facility I posted yesterday: https://lists.01.org/pipermail/linux-nvdimm/2015-October/002512.html. While not very functional for applications it makes testing base DAX mechanisms straightforward.
