JFYI, this commit was the last user of writable_file_mapping_allowed(),
which breaks the x86-defconfig build:
mm/gup.c:1015:13: error: ‘writable_file_mapping_allowed’ defined but not used [-Werror=unused-function]
There's also a now orphan reference to writable_file_mapping_allowed() in
the comment of folio_fast_pin_allowed().
Thanks,
Ingo
