If we have more work to do it makes sense not to plug, and if we don't have more work we are going to sleep. I think the one in xfs_flush_buftarg actually does make sense to keep - we really want to flush out all pending I/O before waiting for it. But I guess for both of these we just want to add an explicit plug/unlug pair to optimize the I/O dispatch. -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
