[Crash-utility] crash help: using list for traversing pages through page.next

Hi all, Recently I found an slub related problem(kmalloc-1024 objects eat tons of memory): # ./slabinfo -l | grep "t-0001024" :t-0001024 46448117 1024 47.5G 4074/505/11608097 4 0 0 99 * Then I make the memroy coredump trying to find out why, it seems something wrong with the slub's cpu_slab(kmem_cache_cpu) list. But as I want to walk through the page list like following, crash seems can't identify: crash> struct page.next,pages,pobjects 0xffffea0049e85140 next = 0xffffea0014533c40 pages = 13511054 pobjects = -545576266 crash> list page.next 0xffffea0049e85140 list: invalid argument: page.next While my usage case is similar to the case in the 'help list' man page: crash> p file_systems file_systems = $1 = (struct file_system_type *) 0xc03adc90 crash> list file_system_type.next -s file_system_type.name,fs_flags c03adc90 So what is wrong, is there a way that I can walk through the page list? thanks in advance~ linfeng
