One also wonders about whether all the RCU stuff is needed on UP. I'm not sure if I grok all the finepoints here, but it looks like the answer is no and that we can make struct_rcu head empty and have call_rcu fall directly through to the callback. This would save something like 16-32 bytes (32/64bit), not to mention a bunch of dinking around with lists and whatnot. So what am I missing? -- Matt Mackall : http://www.selenic.com : Linux development and consulting - 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/ | ||||||||||||
