It's wrong to call this a ring buffer as things won't be completed in any particular order. So you'll need a fourth list head for which buffer elements are free. At which point, you might as well leave it entirely up to the application to manage the allocation of async_syscall structs. It may know it only needs two, or ten thousand, or five per client... -- Mathematics is the supreme nostalgia of our time. - 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/
