Hi all,

After merging the mm tree, today's linux-next build (x86_64 allnoconfig)
failed like this:

In file included from include/linux/suspend.h:5,
                 from arch/x86/kernel/asm-offsets.c:14:
include/linux/swap.h:568:6: warning: no previous prototype for 'swap_free_nr' [-Wmissing-prototypes]
  568 | void swap_free_nr(swp_entry_t entry, int nr_pages)
      |      ^~~~~~~~~~~~
(lots of these)

Caused by commit

  ca23b4d4cae5 ("mm: swap: introduce swap_free_nr() for batched swap_free()")

from the mm-unstable branch of the mm tree.

I have applied the following patch for today.
