And you play tricky games with common_node/device_node of struct dma_chan - one of that lists is never protected, while other is called under RCU and other locks (btw, why does insertion use RCU and deletion in dma_async_device_unregister() does not?). struct ioat_dma_chan - is it somewhere freed? -- Evgeniy Polyakov - 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/ | |||||||||
