* scsi: cxlflash: Combine the send queue locksUma Krishnan2017-06-262-6/+6
| | | | | | | | | | | | | | Currently there are separate spin locks for the two supported I/O queueing models. This makes it difficult to serialize with paths outside the enqueue path. As a design simplification and to support serialization with enqueue operations, move to only a single lock that is used for enqueueing regardless of the queueing model.

* scsi: hisi_sas: redefine hisi_sas_phy.phy_type as u32John Garry2017-06-261-1/+1
| | | | | | | | | | | | | | Element phy_type is a bitmask and it only ever has 2 bits possibly set, and it is overkill to define as a u64, so redefine as a u32. This change resolves static code check complaint that "phy->phy_type &= ~PORT_TYPE_SAS;" would unintentionally clear the high 32 bits as well. Structure hisi_sas_phy is also reordered to ensure packing efficiency. Reported-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Martin K.

* scsi: lpfc: Fix nvme io stoppage after link bounceJames Smart2017-06-261-34/+1
| | | | | | | | | | | | | On link down, transport is calling driver to abort outstanding ios. Driver erroneously rejects the abort if the port indicates it isn't logged in - which will be the case after the link down. Thus, the io can't clean up. This prevents reconnection at the transport level. Fix by allowing abort to proceed.

* scsi: virtio_scsi: let host do exception handlingPaolo Bonzini2017-06-261-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | virtio_scsi tries to do exception handling after the default 30 seconds timeout expires. However, it's better to let the host control the timeout, otherwise with a heavy I/O load it is likely that an abort will also timeout. This leads to fatal errors like filesystems going offline. Disable the 'sd' timeout and allow the host to do exception handling, following the precedent of the storvsc driver. Hannes has a proposal to introduce timeouts in virtio, but this provides an immediate solution for stable kernels too.

* scsi: hisi_sas: create hisi_sas_get_fw_info()John Garry2017-06-192-37/+71
| | | | | | | | | | | | | Move the functionality to retrieve the fw info into a dedicated device type-agnostic function, hisi_sas_get_fw_info(). The reasoning is that this function will be required for future pci-based platforms. Also add some debug logs for failure. Signed-off-by: John Garry <john.garry@huawei.com> Signed-off-by: Martin K.

* scsi: hisi_sas: add pci_dev in hisi_hba structJohn Garry2017-06-194-55/+59
| | | | | | | | | | | | | Since hip08 SAS controller is based on pci device, add hisi_hba.pci_dev for hip08 (will be v3), and also rename hisi_hba.pdev to .platform_dev for clarity. In addition, for common code which wants to reference the controller device struct, add hisi_hba.dev, and change the common code to use it.

| | | | | | | | | Relocate get_ncq_tag_v2_hw() to a common location, as future hw versions will require it. Also rename with "hisi_sas_" prefix for consistency.
