please doin't use the iomap_* namespace even for static functions in
filesystem code. This really doesn't have anything to do with iomap
except that whatever fuse sets up is used to fill an iomap.
i.e. fuse_setup_new_dax_mapping() would be far more appropriate
name.

ditto: fuse_upgrade_dax_mapping().

Cheers,

Dave.
