Keith Busch authored
The sysfs group containing the cmb attributes is registered before the driver knows if they need to be visible or not. Update the group when cmb attributes are known to exist so the visibility setting is correct.

When validating drafted SPDK ublk target, in a case that assigning large queue depth to multiqueue ublk device, ublk target would run into a weird incorrect state. During rounds of review and debug, An overflow bug was found in ublk driver. In ublk_cmd.h, UBLK_MAX_QUEUE_DEPTH is 4096 which means each ublk queue depth can be set as large as 4096. But when setting qd for a ublk device, sizeof(struct ublk_queue) + depth * sizeof(struct ublk_io) will be larger than 65535 if qd is larger than 2728. Then queue_size is overflowed, and ublk_get_queue() references a wrong pointer position. The wrong content of ublk_queue elements will lead to out-of-bounds memory access. Extend queue_size in ublk_device as "unsigned int".

Polling the completion can progress the request state to IDLE, either inline with the completion, or through softirq. Either way, the state may not be COMPLETED, so don't check for that. We only care if the state isn't IN_FLIGHT. This is fixing an issue where the driver aborts an IO that we just completed.

This is a functional revert of c76b8308 ("nvme-apple: fix controller shutdown in apple_nvme_disable"). The commit broke suspend/resume since apple_nvme_reset_work() tries to disable the controller on resume. This does not work for the apple NVMe controller since register access only works while the co-processor firmware is running. Disabling the NVMe controller in the shutdown path is also required for shutting the co-processor down. The original code was appropriate for this hardware. Add a comment to prevent a similar breaking changes in the future.

When there are no read queues read requests will be assigned a default queue on allocation. However, blk_mq_get_cached_request() is not prepared for that and will fail all attempts to grab read requests from the cache. Worst case it doubles the number of requests allocated, roughly half of which will be returned by blk_mq_free_plug_rqs(). It only affects batched allocations and so is io_uring specific. For reference, QD8 t/io_uring benchmark improves by 20-35%.

The updating of 'bfqg->ref' should be protected by 'bfqd->lock', however, during code review, we found that bfq_pd_free() update 'bfqg->ref' without holding the lock, which is problematic: 1) bfq_pd_free() triggered by removing cgroup is called asynchronously; 2) bfqq will grab bfqg reference, and exit bfqq will drop the reference, which can concurrent with 1). Unfortunately, 'bfqd->lock' can't be held here because 'bfqd' might already be freed in bfq_pd_free(). Fix the problem by using atomic refcount apis.
