[Crash-utility] [PATCH]: nr_node_ids

Hi all, I'm wondering about the use of the kernel 'nr_node_ids' variable in memory.c. In kmem_cache_downsize(), vt->kmem_cache_len_nodes defaults to 1 when 'nr_node_ids' isn't present. But in vm_init() an error message is printed in the same case. The reason I'm asking is that I'm getting that error "unable to initialize kmem slab cache subsystem" on a 3.4 kernel. Having vm_init() default to vt->kmem_cache_len_nodes=1 as well seems to bring up the slab subsystem, although I'm getting a couple of "kmem: vm_area_struct: full list: slab: <nn1> bad next pointer: <nn2>" mixed into my kmem -S output. I have no idea if it's related. Regards, Per
