The kmem_cache_cpu structures are allocated using DEFINE_PER_CPU. The per cpu areas should be dynamically allocated as necessary. There is work in progress by Mike Travis to do that. You are right in that (on x86_64 at least) we define a static array for all processors. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
