Hi all, After merging the slab tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: kernel/bpf/memalloc.c: In function 'bpf_mem_free': kernel/bpf/memalloc.c:613:33: error: implicit declaration of function '__ksize'; did you mean 'ksize'? [-Werror=implicit-function-declaration] 613 | idx = bpf_mem_cache_idx(__ksize(ptr - LLIST_NODE_SZ)); | ^~~~~~~ | ksize Caused by commit 8dfa9d554061 ("mm/slab_common: move declaration of __ksize() to mm/slab.h") interacting with commit 7c8199e24fa0 ("bpf: Introduce any context BPF specific memory allocator.") from the bpf-next tree. I have reverted the slab tree commit for today. -- Cheers, Stephen Rothwell
