| |
Hi Jens,
In blk_mq_map_swqueue(), all the blk_mq_hw_ctx's nr_ctx are set to zero, and then each blk_mq_ctx's index_hw is set to nr_ctx. I think the index_hw means the index of the hardware queue that map to this software queue, so maybe index_hw should be set to blk_mq_hw_ctx's queue_num.
I'm a student and I probably have misunderstood this code, please help me to resolve this confusion. Thank you.
static void blk_mq_map_swqueue(struct request_queue *q) { ......... queue_for_each_hw_ctx(q, hctx, i) { ......... hctx->nr_ctx = 0; } ......... queue_for_each_ctx(q, ctx, i) { ......... ctx->index_hw = hctx->nr_ctx; ......... } }
