Hi all,
After merging the mm tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:
mm/memory.c: In function 'do_swap_page':
mm/memory.c:4169:17: error: implicit declaration of function 'count_mthp_stat' [-Werror=implicit-function-declaration]
4169 | count_mthp_stat(folio_order(folio), MTHP_STAT_ANON_SWPIN_REFAULT);
| ^~~~~~~~~~~~~~~
mm/memory.c:4169:53: error: 'MTHP_STAT_ANON_SWPIN_REFAULT' undeclared (first use in this function)
4169 | count_mthp_stat(folio_order(folio), MTHP_STAT_ANON_SWPIN_REFAULT);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
mm/memory.c:4169:53: note: each undeclared identifier is reported only once for each function it appears in
cc1: some warnings being treated as errors
Caused by commits
d46de7357458 ("mm: add per-order mTHP anon_alloc and anon_alloc_fallback counters")
37a4ecbf36cb ("mm: add per-order mTHP swpin_refault counter")
I have applied the following patch for today:
