Subject: [SLUB] change kmem_cache->align to record the real alignment
Date: Thu, 30 Jul 2009 11:28:11 +0800 [thread overview]
Message-ID: <1248924491.2560.725.camel@ymzhang> (raw)
kmem_cache->align records the original align parameter value specified
by users. Function calculate_alignment might change it based on cache
line size. So change kmem_cache->align correspondingly.
