Subject: Re: [syzbot] [mm?] kernel BUG in const_folio_flags (2)

Hello,

syzbot tried to test the proposed patch but the build/boot failed:

./include/linux/page-flags.h:309:29: error: implicit declaration of function 'folio_nr_pages'; did you mean 'folio_page'? [-Werror=implicit-function-declaration]
./include/linux/mm.h:2056:20: error: conflicting types for 'folio_nr_pages'; have 'long int(const struct folio *)'

Tested on:
