If you give an optional string pattern to "help -o", you will
see just those entries that match, instead of all ~500 entries.
So, taking a 2.6.9 kernel, here's what was initialized
for the kmem_cache_s structure entries needed:

crash> help -o kmem_cache
                  offset_table:
          kmem_cache_s_c_nextp: -1
           kmem_cache_s_c_name: -1
            kmem_cache_s_c_num: -1
       kmem_cache_s_c_org_size: -1
          kmem_cache_s_c_flags: -1
         kmem_cache_s_c_offset: -1
         kmem_cache_s_c_firstp: -1
       kmem_cache_s_c_gfporder: -1
          kmem_cache_s_c_magic: -1
          kmem_cache_s_c_align: -1
              kmem_cache_s_num: 184
             kmem_cache_s_next: 244
             kmem_cache_s_name: 240
          kmem_cache_s_objsize: 176
            kmem_cache_s_flags: 180
         kmem_cache_s_gfporder: 200
            kmem_cache_s_slabs: -1
       kmem_cache_s_slabs_full: -1
    kmem_cache_s_slabs_partial: -1
       kmem_cache_s_slabs_free: -1
          kmem_cache_s_cpudata: -1
       kmem_cache_s_colour_off: 212
            kmem_cache_s_array: 0
            kmem_cache_s_lists: 136

                    size_table:
                  kmem_cache_s: 252

                   array_table:
             kmem_cache_s_name: 0
           kmem_cache_s_c_name: 0
            kmem_cache_s_array: 32
          kmem_cache_s_cpudata: 0
crash>

Again, the -1 entries are for older kernels and are
irrelevant.  It's just the initialization for the other
11 entries that are non-zero need to be addressed,

Just to be clear, those entries containing "0" are
are legitimate, required, entries.
