Hello,

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

./include/linux/rmap.h:220:16: error: initializing 'struct page *' with an expression of type 'typeof (page)' (aka 'const struct page *') discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
./include/linux/rmap.h:223:5: error: assigning to 'struct page *' from 'const struct page *' discards qualifiers [-Werror,-Wincompatible-pointer-types-discards-qualifiers]
