AFAIK, the existence of the slab allocator is to reduce the external fragmentation of Buddy System.(Calls to Buddy system 'dirties' the cache).
However, the slab itself introduces internal fragmentation caused by mismatch of the requested size and the allocated one.
Correct me if i am wrong.

Hi all,
In theory the slab allocation causes no internal fragmentation, but in
the Linux kernel implementation it just reduces the internal
fragmentation, since the internal fragmentation still exists.
Is my opinion correct?
