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.
