软件队列(对应内核struct blk_mq_ctx数据结构):blk-mq中为每个CPU分配一个软件队列(soft context dispatch queue),由于每个CPU有单独的队列,所以每个CPU上的这些I/O操作可以同时进行(需要注意的是:同一个CPU中的进程间依然存在锁竞争的问题),而不存在锁竞争问题; 硬件队列(对应内核struct blk_mq_hw_ctx数据结构,...

这个request_queue 的初始化过程在 blk_mq_init_queue 中。它会调用 blk_mq_init_allocated_queue->blk_queue_make_request。在这里面,我们可以将 make_request_fn 函数设置为 blk_mq_make_request,也就是说,一旦上层有写入请求,我们就通过 blk_mq_make_request 这个函数,将请求放入 request_queue 队列中。 ...
