That is normal. Linux tries to put all memory to use and will free on
demand.

Compile the slabinfo tool.
gcc -o slabinfo linux/Documentation/vm/slabinfo.c
Then you can do
slabinfo -T
to get an overview of how much is used by slabs. But I do not see that
slabs are using an excessive amount. So toying around with slabinfo is
not going to get you anywhere.
