One of them is also used for registering the other driver, the other one is entirely useless after the large scale cleanup that Alan Cox did back in 2007. The compiler warns about this whenever the driver is built-in: drivers/scsi/initio.c:131:29: warning: 'i91u_pci_devices' defined but not used [-Wunused-variable] This removes the extraneous table and the warning.

While the compiler does inline get_in_stor_device() (and other static functions) in the call chain in the interrupt path, the compiler is repeatedly inlining the call to get_in_stor_device() each time it is invoked. The return value of get_in_stor_device() can be cached in the interrupt path since there is higher level serialization in place to ensure correct handling when the module unload races with the processing of an incoming message from the host. Optimize this code path by caching the pointer to storvsc_device and passing it as an argument. Signed-off-by: K. Y.

Ochs" Date: Mon, 14 Dec 2015 14:55:44 -0600 Subject: cxlflash: Fix to avoid virtual LUN failover failure Applications which use virtual LUN's that are backed by a physical LUN over both adapter ports may experience an I/O failure in the event of a link loss (e.g. cable pull). Virtual LUNs may be accessed through one or both ports of the adapter. This access is encoded in the translation entries that comprise the virtual LUN and used by the AFU for load-balancing I/O and handling failover scenarios. In a link loss scenario, even though the AFU is able to maintain connectivity to the LUN, it is up to the application to retry the failed I/O. When applications are unaware of the virtual LUN's underlying topology, they are unable to make a sound decision of when to retry an I/O and therefore are forced to make their reaction to a failed I/O absolute. The result is either a failure to retry I/O or increased latency for scenarios where a retry is pointless. To remedy this scenario, provide feedback back to the application on virtual LUN creation as to which ports the LUN may be accessed. LUN's spanning both ports are candidates for a retry in a presence of an I/O failure. Signed-off-by: Matthew R. Ochs Acked-by: Manoj Kumar Reviewed-by: Uma Krishnan Signed-off-by: Martin K.

As per the design, the Accelerator Function Unit (AFU) for this new IBM CXL Flash Adapter retains the same host interface as the previous generation. For the early prototypes of the new card, the driver with this change behaves exactly as the driver prior to this behaved with the earlier generation card. Therefore, no card specific programming has been added. These card specific changes can be staged in later if needed. Signed-off-by: Manoj N. Kumar Acked-by: Matthew R.
