Al has nak'd the uaccess related changes, and I'll need to rework those patches to move the pmem routines into lib/iov_iter.c directly. That doesn't affect the dax_device and dax_operations work, so I'm still looking to move forward with that change. That reduces the set targeting 4.12 to just the first 18 patches from this series: Dan Williams (18): device-dax: rename 'dax_dev' to 'dev_dax' dax: refactor dax-fs into a generic provider of 'struct dax_device' instances dax: add a facility to lookup a dax device by 'host' device name dax: introduce dax_operations pmem: add dax_operations support axon_ram: add dax_operations support brd: add dax_operations support dcssblk: add dax_operations support block: kill bdev_dax_capable() dax: introduce dax_direct_access() dm: add dax_device and dax_operations support dm: teach dm-targets to use a dax_device + dax_operations ext2, ext4, xfs: retrieve dax_device for iomap operations Revert "block: use DAX for partition table reads" filesystem-dax: convert to dax_direct_access() block, dax: convert bdev_dax_supported() to dax_direct_access() block: remove block_device_operations ->direct_access() x86, dax, pmem: remove indirection around memcpy_from_pmem()
