I'm working on converting ext4 to the new iomap infrastructure. Once that
is done, it can use new DAX helpers for PMD faults easily.

This series made dax_pmd_fault return VM_FAULT_FALLBACK in [PATCH v6 09/17] 
dax: remove dax_pmd_fault(). 
That essentially disable dax pmd for ext4. Any plans to fix that ?
