The initial purpose was to obtain the type of each slab through a simple command 'cat proc/slabinfo'. So here, my intention is not to update all slabinfo-related tools for the time being, but to modify the version number of proc/slabinfo and further display the results of using the command.

The note here means what changes will occur after we modify the version number of proc/slabinfo to 2.2. As for the replacement of tools/mm/slabinfo (that inspired by Christoph’s suggestions), it will be implemented in the next version or even the later version.
Thanks!
