Hi all, After merging the akpm-current tree, today's linux-next build (sparc defconfig) failed like this: mm/slab.c: In function '___cache_free': mm/slab.c:3471:2: error: implicit declaration of function '__free_one'; did you mean '__free_page'? [-Werror=implicit-function-declaration] __free_one(ac, objp); ^~~~~~~~~~ __free_page Caused by commit 1420b22124be ("mm/slab: add naive detection of double free") __free_one() is ony defined when CONFIG_NUMA is set but used more generally. I have reverted that commit for today. -- Cheers, Stephen Rothwell
