kmem_cache is a frequently used data in kernel. During the code reading, I found maybe we could save some space in some cases.
1. On 64bit arch, type int will occupy a word if it doesn't sit well. 2. cpu_slab->partial is just used when CONFIG_SLUB_CPU_PARTIAL is set 3. cpu_partial is just used when CONFIG_SLUB_CPU_PARTIAL is set, while just save some space on 32bit arch.
Wei Yang (3): mm/slub: pack red_left_pad with another int to save a word mm/slub: wrap cpu_slab->partial in CONFIG_SLUB_CPU_PARTIAL mm/slub: wrap kmem_cache->cpu_partial in config CONFIG_SLUB_CPU_PARTIAL
