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) | ^~ In file included from include/asm-generic/bug.h:22, from arch/powerpc/include/asm/bug.h:159, from include/linux/bug.h:5, from include/linux/thread_info.h:13, from include/asm-generic/preempt.h:5, from ./arch/powerpc/include/generated/asm/preempt.h:1, from include/linux/preempt.h:78, from include/linux/spinlock.h:56, from include/linux/mmzone.h:8, from include/linux/gfp.h:7, from include/linux/slab.h:15, from mm/slab_common.c:7: mm/slab_common.c:604:53: error: 'struct kmem_cache' has no member named 'usersize' 604 | pr_cont(" size %u", kp.kp_slab_cache->usersize); | ^~ include/linux/printk.h:429:33: note: in definition of macro 'printk_index_wrap' 429 | _p_func(_fmt, ##__VA_ARGS__); \ | ^~~~~~~~~~~ include/linux/printk.h:542:9: note: in expansion of macro 'printk' 542 | printk(KERN_CONT fmt, ##__VA_ARGS__) | ^~~~~~ mm/slab_common.c:604:17: note: in expansion of macro 'pr_cont' 604 | pr_cont(" size %u", 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.
