Very slick!

I still think Ritesh's patches are easier for backporting because they are
mostly contained within the ext4/overlayfs subsystems and your patch
can follow up as interface cleanup.

I would use as generic helper name generic_fiemap_checks()
akin to generic_write_checks() and generic_remap_file_range_prep() =>
generic_remap_checks().

Thanks,
Amir.
