[v4.17-stable v2 0/5] Fix DM DAX handling

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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
