We get a warning for the fas216 driver when it is compiled as a loadable module, as the __setup() functions are never called then: scsi/arm/fas216.c:101:19: warning: 'fas216_log_setup' defined but not used [-Wunused-function] static int __init fas216_log_setup(char *str) This adds an #ifndef MODULE around the definition to shut up the warning and clarify for the reader when it is used or not.

The calc_sync_xfer function is only used if CONFIG_SCSI_ACORNSCSI_SYNC is set, otherwise we get a compiler warning: scsi/arm/acornscsi.c:680:15: warning: 'calc_sync_xfer' defined but not used [-Wunused-function] unsigned char calc_sync_xfer(unsigned int period, unsigned int offset) This marks the function as __maybe_unused to shut up the warning and silently drop the function in the object code when there is no caller.

The seq_mpt_print_ioc_summary function is used for the /proc/mpt/iocN/summary implementation and never gets called when CONFIG_PROC_FS is disabled: drivers/message/fusion/mptbase.c:6851:13: warning: 'seq_mpt_print_ioc_summary' defined but not used [-Wunused-function] static void seq_mpt_print_ioc_summary(MPT_ADAPTER *ioc, struct seq_file *m, int showlan) This adds an #ifdef to hide the function definition in that case and avoid the warning.

The fdomain SCSI host driver is one of the last remaining drivers that manually search the PCI bus using pci_get_device rather than registering a pci_driver instance. This means the module device table is unused when the driver is built-in, and we get a warning about it: drivers/scsi/fdomain.c:1773:29: warning: 'fdomain_pci_tbl' defined but not used [-Wunused-variable] To avoid the warning, this adds another #ifdef around the table definition.

This removes a redundant code block that will either be executed if the ENABLE_FCP_RING_POLLING flag is set in phba->cfg_poll or not. The code is just duplicated in both cases, hence we unify it again. This probably is a left over from some sort of refactoring. Signed-off-by:

Change the MTMKPART operation of the MTIOCTOP ioctl so that it works also with current drives (LTO-5/6, etc.). Send a separate FORMAT MEDIUM command if the partition mode page indicates that this is required. Use LOAD to position the tape at the beginning of tape. The operation is extended so that if the argument is negative, its absolute value specifies the size of partition 0, which is the physically first partition of the tape. Signed-off-by:

The hisi_sas driver is required to support both device tree and ACPI. The scanning of the device properties now uses the Unified Device Properties API, which serves both OF and ACPI. Since syscon is not supported by ACPI, syscon is only used in the driver when device tree is used. Signed-off-by:

Connection resets observed from some targets when NOP-Out with wrong ExpStatSn is sent. FW keeps track of StatSn and fills up ExpStatSn accordingly. The header filled up by the stack needs to be modified by driver to clear ExpStatSn. If the field is not cleared, FW recalculates ExpStatSn and wrong offset'ed ExpStatSn is seen in the wire trace.

WARN_ON(atomic_read(&mccq->used) >= mccq->len) seen when FW gets into UE. MCCQ overflow is happening because driver discards any new request and frees up the tag. The tag allocation controls the number of MCC WRB posted. It is being replenished but WRBs are not hence the WARN_ON. Allocation and freeing of WRB and tags for MCC is now done in one place. This helps to achieve proper accounting of WRB indices and MCC tags. Signed-off-by:

During EEH PCI hotplug activity kernel unloads and loads the driver, causing character device to be unregistered(aac_remove_one).When the driver is loaded back using aac_probe_one the character device needs to be registered again for the AIF management tools to work.
