Hi all,
After merging the mm tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
In file included from arch/arm/mm/flush.c:17:
include/linux/hugetlb.h:1063:5: warning: no previous prototype for 'replace_free_hugepage_folios' [-Wmissing-prototypes]
1063 | int replace_free_hugepage_folios(unsigned long start_pfn, unsigned long end_pfn)
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
(and many more)
Caused by commit
7e5670da4517 ("mm: replace free hugepage folios after migration")
from the mm-unstable branch of the mm tree.
I have applied the following fix for today.
