Hi all,
After merging the mm tree, today's linux-next build (powerpc allnoconfig)
failed like this:
In file included from include/linux/suspend.h:5,
from arch/powerpc/mm/mem.c:17:
include/linux/swap.h:581:12: error: 'folio_alloc_swap' defined but not used [-Werror=unused-function]
581 | static int folio_alloc_swap(struct folio *folio, gfp_t gfp_mask)
| ^~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
(and many, many more - some just warnings)
Caused by commit
436a263c3c8e ("mm, swap: simplify folio swap allocation")
from the mm-unstable branch of the mm tree.
I have applied the following patch for today.
