From: Ira Weiny <ira.weiny@intel.com>

Enable the same per file DAX support in ext4 as was done for xfs.  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.

Changes from V0:
	Collect reviews
	Fix up setting don't cache in ioctl code
	Add FS_DAX_FL flag for consistency
