Hi all, After merging the folio tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: mm/mmap.c: In function 'do_mas_align_munmap': mm/mmap.c:2373:25: error: implicit declaration of function 'munlock_vma_pages_all'; did you mean 'munlock_vma_page'? [-Werror=implicit-function-declaration] 2373 | munlock_vma_pages_all(next); | ^~~~~~~~~~~~~~~~~~~~~ | munlock_vma_page mm/mmap.c: In function 'do_brk_munmap': mm/mmap.c:2906:17: error: implicit declaration of function 'munlock_vma_pages_range'; did you mean 'count_vma_pages_range'? [-Werror=implicit-function-declaration] 2906 | munlock_vma_pages_range(&unmap, newbrk, oldbrk); | ^~~~~~~~~~~~~~~~~~~~~~~ | count_vma_pages_range This is undoubtably due to something I missed in the merge resolution, so I am giving up on merging the folio tree again today and am back to the version from next-20220204 again. -- Cheers, Stephen Rothwell
