These two fixes are to the now-disabled per-inode DAX support in XFS. I started working on these in the v4.13 timeframe before the per-inode DAX feature was turned off.
I realize that they may not be critical right now since the per-inode DAX feature is turned off, but I think that if we ever do re-enable that feature we will want these two issues to have been fixed. I also do think that they are both vaulable for stable kernels. These used to be part of my ext4 per-inode enabling: https://lkml.org/lkml/2017/9/5/748 But I've since split that into a series of XFS bug fixes (these two) and a series of ext4 bug fixes.
