Requiring the block mappings to be entirely async is why we never went for full buffered aio. What would seem more useful is to offload all readahead to workqueues to make sure they never block the caller for sys_readahead or if we decide to readahead for the nonblocking read. I tried to implement this, but I couldn't find a good place to hang the work_struct for it off. If we decide to dynamically allocate the ra structure separate from struct file that might be an obvious place. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
