This series builds and depends on the V11 series for xfs.[1] This passes the same xfstests test as XFS. The only issue is that this modifies the old mount option parsing code rather than waiting for the new parsing code to be finalized. This series starts with 3 fixes which include making Verity and Encrypt truly mutually exclusive from DAX. I think these first 3 patches should be picked up for 5.8 regardless of what is decided regarding the mount parsing.
