No, that's entirely incorrect. IFF a device supports multiple hardware queues we only submit I/O from CPUs (there might be more than one) this queue is bound to. With the single hardware queue supported by most hardware submissions can and will happen from any CPU. Note that this patchset doesn't even support multiple hardware queues yet, although it should be fairly simple to add once the low level driver support is ready. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
