- Deprecated and scheduled for removal in a few cycles. SLUB
- recommended as replacement. CONFIG_SLUB_TINY can be considered
- on systems with 16MB or less RAM.

- If you need SLOB to stay, please contact linux-mm@kvack.org and

- SLOB replaces the stock allocator with a drastically simpler
- allocator. SLOB is generally more space efficient but
- does not perform as well on large systems.
