This is a v4.17-stable backport of my "Fix DM DAX handling" series which had backport collisions.
Greg, please let me know if I need to adjust anything in my backport formatting.
---
Changes since v1: * Fixed formatting of my "commit X upstream." lines to include the full hash to match other existing backports in stable.
* Fixed a few of the commit IDs which were from a dev branch and not the actual upstream commit ID.
* Pulled in updated tags and changlog wording differences from upstream commits vs commits in my dev branch.
Darrick J. Wong (1): fs: allow per-device dax status checking for filesystems
Dave Jiang (1): dax: change bdev_dax_supported() to support boolean returns
Ross Zwisler (3): pmem: only set QUEUE_FLAG_DAX for fsdax mode dax: check for QUEUE_FLAG_DAX in bdev_dax_supported() dm: prevent DAX mounts if not supported
