kern: make struct kmem_cache fit into two cache lines
Previously, the size of struct kmem_cache was 136 bytes, just eight bytes larger than 128 bytes, which is typically two cache lines on today's CPUs. By reducing the size of the name field which holds a human-readable description by eight bytes to 24 bytes, the struct kmem_cache can be made fit into two cache lines. This change should not affect the usefulness of this field. For reference, the length of the largest hard-coded name is 17. * kern/slab.h (KMEM_CACHE_NAME_SIZE): Define to 24.
