2021-10-18block/sx8: add error handling support for add_disk()Luis Chamberlain
We never checked for errors on add_disk() as this function returned void. Now that this is fixed, use the shiny new error handling. A completion is used to notify the initial probe what is happening and so we must defer error handling on completion. Do this by remembering the error and using the shared cleanup function. The tags are shared and so are hanlded later for the driver already. Signed-off-by: Luis Chamberlain <mcgrof@kernel.org> Signed-off-by: Jens Axboe <axboe@kernel.dk>

2021-10-18null_blk: poll queue supportJens Axboe
There's currently no way to experiment with polled IO with null_blk, which seems like an oversight. This patch adds support for polled IO. We keep a list of issued IOs on submit, and then process that list when mq_ops->poll() is invoked. A new parameter is added, poll_queues. It defaults to 1 like the submit queues, meaning we'll have 1 poll queue available.

2021-10-18nvme: wire up completion batching for the IRQ pathJens Axboe
Trivial to do now, just need our own io_comp_batch on the stack and pass that in to the usual command completion handling. I pondered making this dependent on how many entries we had to process, but even for a single entry there's no discernable difference in performance or latency. Running a sync workload over io_uring: t/io_uring -b512 -d1 -s1 -c1 -p0 -F1 -B1 -n2 /dev/nvme1n1 /dev/nvme2n1 yields the below performance before the patch: IOPS=254820, BW=124MiB/s, IOS/call=1/1, inflight=(1 1) IOPS=251174, BW=122MiB/s, IOS/call=1/1, inflight=(1 1) IOPS=250806, BW=122MiB/s, IOS/call=1/1, inflight=(1 1) and the following after: IOPS=255972, BW=124MiB/s, IOS/call=1/1, inflight=(1 1) IOPS=251920, BW=123MiB/s, IOS/call=1/1, inflight=(1 1) IOPS=251794, BW=122MiB/s, IOS/call=1/1, inflight=(1 1) which definitely isn't slower, about the same if you factor in a bit of variance. For peak performance workloads, benchmarking shows a 2% improvement. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-10-18nvme: add support for batched completion of polled IOJens Axboe
Take advantage of struct io_comp_batch, if passed in to the nvme poll handler. If it's set, rather than complete each request individually inline, store them in the io_comp_batch list. We only do so for requests that will complete successfully, anything else will be completed inline as before. Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2021-10-18block: add a struct io_comp_batch argument to fops->iopoll()Jens Axboe
struct io_comp_batch contains a list head and a completion handler, which will allow completions to more effciently completed batches of IO. For now, no functional changes in this patch, we just define the io_comp_batch structure and add the argument to the file_operations iopoll handler.

2021-10-18block: switch polling to be bio basedChristoph Hellwig
Replace the blk_poll interface that requires the caller to keep a queue and cookie from the submissions with polling based on the bio. Polling for the bio itself leads to a few advantages: - the cookie construction can made entirely private in blk-mq.c - the caller does not need to remember the request_queue and cookie separately and thus sidesteps their lifetime issues - keeping the device and the cookie inside the bio allows to trivially support polling BIOs remapping by stacking drivers - a lot of code to propagate the cookie back up the submission path can be removed entirely.

It is a bit confusing that there is BLKDEV_MAX_RQ and MAX_SCHED_RQ, as the name BLKDEV_MAX_RQ would imply the max requests always, which it is not.

2021-10-17brd: reduce the brd_devices_mutex scopeTetsuo Handa
As with commit 8b52d8be86d72308 ("loop: reorder loop_exit"), unregister_blkdev() needs to be called first in order to avoid calling brd_alloc() from brd_probe() after brd_del_one() from brd_exit(). Then, we can avoid holding global mutex during add_disk()/del_gendisk() as with commit 1c500ad706383f1a ("loop: reduce the loop_ctl_mutex scope").
