Hi-
Some of my CI runs have started failing to build v6.13+ kernels with:
mm/vmscan.c: In function ‘shrink_folio_list’:
mm/vmscan.c:1082:21: error: implicit declaration of function
‘folio_contain_hwpoisoned_page’ [-Wimplicit-function-declaration]
1082 | if (folio_contain_hwpoisoned_page(folio)) {
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
make[3]: *** [scripts/Makefile.build:196: mm/vmscan.o] Error 1
make[2]: *** [scripts/Makefile.build:442: mm] Error 2
make[2]: *** Waiting for unfinished jobs....
make[1]: *** [/data/linux-stable-rc/Makefile:1989: .] Error 2
make: *** [Makefile:251: __sub-make] Error 2
Is there a .config change I need to prevent this failure?

I don't see why folio_contain_hwpoisoned_page() wouldn't be declared.
Could you include your .config?

I assumed linux-mm would bounce an attachment. But it turns out I have a
sample .config in a public git repo:
https://github.com/chucklever/kdevops/blob/queue-6-13/playbooks/roles/bootlinux/templates/config-kdevops
The failure seems to be intermittent.

I have not seen a repeat of this issue.
