Hi all,
After merging the slab tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:
mm/slab_common.c: In function 'kmem_dump_obj':
mm/slab_common.c:603:49: error: 'struct kmem_cache' has no member named 'usersize'
603 | if (kp.kp_slab_cache && kp.kp_slab_cache->usersize)

Caused by commit
3cdb7b6ad16a ("mm, slab: ignore hardened usercopy parameters when disabled")
I have used the slab tree from next-20221123 for today.
