Hmmmm... Maybe .. The locking rules are not changed at all by this patch. The cmpxchg_local is only used for the per cpu object list. The per cpu slabs are frozen. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
