Ira Weiny	6c0d077ff8	fs/ext4: Disallow verity if inode is DAX Verity and DAX are incompatible. Changing the DAX mode due to a verity flag change is wrong without a corresponding address_space_operations update. Make the 2 options mutually exclusive by returning an error if DAX was set first. (Setting DAX is already disabled if Verity is set first.)

fs/ext4: Disallow verity if inode is DAX

Verity and DAX are incompatible.  Changing the DAX mode due to a verity
flag change is wrong without a corresponding address_space_operations
update.

Make the 2 options mutually exclusive by returning an error if DAX was
set first.

(Setting DAX is already disabled if Verity is set first.)
