Then we tromp the stupid private implementations in slob.c and slub.c. Then we wonder why x86 uses a custom cache_line_size(), but still uses L1_CACHE_BYTES for its L1_CACHE_ALIGN(). Once we've answered that, we look at your + /* + * We should make sure each CPU gets private memory. + */ + size = roundup(size, cache_line_size()); and wonder whether it should have used L1_CACHE_ALIGN(). I think I'd better stop looking. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
