Per the suggestion from David [1], this implementation dumps single slab cache if its size is over 10% of total system memory. In current implementation, the ration is fixed as 10%.
To get the size of total system memory patch #1 extract the common code from show_mem() so that the code can be used by checking the ratio. The patchset is based on the mmotm tree.
