No, I don't want the DAX mount option documented. As the code says:
#define XFS_MOUNT_DAX (1ULL << 62) /* TEST ONLY! */
The mount option needs to go away and be replaced by on-disk inheritable per-inode flags. I have the kernel patch to do this, but I have not written the xfs_io patch to get/set/clear the flags yet.
Cheers,
Dave.

Ok. I'll resend the other minor fixups on their own.
