You should do the right things instead of stating irrelevant things
in your cover letter. As said in my last mail: look at the VM_MIXEDMAP
flag and how it is used by DAX, and you'll get out of the vma splitting
business in the fault path.

If the fs/dax.c code scares you take a look at drivers/dax/device.c
