But it only needs to check if it's zero when suspending the raid. So we can switch atomic to percpu to improve the performance. After switching active_io to percpu type, we use the state of active_io to judge if the raid device is suspended. And we don't need to wake up ->sb_wait in md_handle_request anymore. It's done in the callback function which is registered when initing active_io. The argument mddev->suspended is only used to count how many users are trying to set raid to suspend state.

2023-02-01loop: Improve the hw_queue_depth kernel module parameter implementationBart Van Assche
Make the following minor changes which were reported by colleagues while reviewing this code: - Remove the parentheses from around the LOOP_DEFAULT_HW_Q_DEPTH definition since these are superfluous. - Accept other number formats than decimal, e.g. hexadecimal. - Do not set hw_queue_depth to an out-of-range value, even if that value won't be used. - Use the LOOP_DEFAULT_HW_Q_DEPTH macro in the kernel module parameter description to prevent that the description gets out of sync.

2023-02-01nvme: mask CSE effects for security receiveKeith Busch
The nvme driver will freeze the IO queues in response to an admin command with CSE bits set. These bits notify the host that the command that's about to be executed needs to be done exclusively, hence the freeze. The Security Receive command is often reported by multiple vendors with CSE bits set. The reason for this is that the result depends on the previous Security Send. This has nothing to do with IO queues, though, so the driver is taking an overly cautious response to seeing this passthrough command, while unable to fufill the intended admin queue action. Rather than freeze IO during this harmless command, mask off the effects. This freezing is observed to cause IO latency spikes when host software periodically validates the security state of the drives.

2023-02-01nvme: remove nvme_execute_passthru_rqChristoph Hellwig
After moving the nvme_passthru_end call to the callers of nvme_execute_passthru_rq, this function has become quite pointless, so remove it. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Jens Axboe <axboe@kernel.dk> Reviewed-by: Chaitanya Kulkarni <kch@nvidia.com>
2023-02-01nvme-pci: place descriptor addresses in iodKeith Busch
The 'struct nvme_iod' space is appended at the end of the preallocated 'struct request', and padded to the cache line size. This leaves some free memory (in most kernel configs) up for grabs. Instead of appending the nvme data descriptor addresses after the scatterlist, inline these for free within struct nvme_iod. There is now enough space in the mempool for 128 possibe segments. And without increasing the size of the preallocated requests, we can hold up to 5 PRP descriptor elements, allowing the driver to increase its max transfer size to 8MB.

2023-02-01nvme-pci: use mapped entries for sgl decisionKeith Busch
The driver uses the dma entries for setting up its command's SGL/PRP lists. The dma mapping might have fewer entries than the physical segments, so check the dma mapped count to determine which nvme data layout method is more optimal.

2023-02-01nvme-pci: remove SGL segment descriptorsKeith Busch
The max segments this driver can see is 127, well below the 256 threshold needed to add an nvme sgl segment descriptor. Remove all the useless checks and dead code.

2023-02-01nvme-auth: don't use NVMe status codesHannes Reinecke
NVMe status codes are part of the wire protocol, and shouldn't be fabricated in the stack. So with this patch the authentication code is switched over to use error codes; as a side effect authentication failures due to internal error won't be retried anymore. But that shouldn't have happened anyway. Signed-off-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Sagi Grimberg <sagi@grimberg.me> Signed-off-by: Christoph Hellwig <hch@lst.de>
2023-02-01nvme-fabrics: clarify AUTHREQ result handlingHannes Reinecke
The NVMe 2.0 spec defines the ATR and ASCR bits in the AUTHREQ connect response field to be mutually exclusive. So to clarify the handling here switch the AUTHREQ handling to use the bit definitions and check for both bits. And while we're at it, add a message to the user that secure concatenation is not supported (yet).

In nvme_alloc_io_tag_set(), the connect_q pointer should be set to NULL in case of error to avoid potential invalid pointer dereferences. Signed-off-by: Maurizio Lombardi <mlombard@redhat.com> Reviewed-by: Chaitanya Kulkarni <kch@nvidia.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2023-02-01nvme: clear the request_queue pointers on failure in nvme_alloc_admin_tag_setMaurizio Lombardi
If nvme_alloc_admin_tag_set() fails, the admin_q and fabrics_q pointers are left with an invalid, non-NULL value. Other functions may then check the pointers and dereference them, e.g. in nvme_probe() -> out_disable: -> nvme_dev_remove_admin(). Fix the bug by setting admin_q and fabrics_q to NULL in case of error. Also use the set variable to free the tag_set as ctrl->admin_tagset isn't initialized yet.
