I can't find out the answer

[gis88530]

Hello,

I want to calculate the total memory usage of kernel.
I wonder that we just need to add these(*1) in slabinfo or 
we need to add each line(*1 and *2) in slabinfo. Thanks.
AND
I know the size of size-512 is 512 bytes, but I want to know
the size of tcp_tw_bucket, tcp_open_request, etc.
How can I find out this answer? Thanks a lot.

1) you want to use only the values from the second column

2) the sizes of the structures you want to know are somewhere
   in the kernel header files, grep should be able to find them
