This ensures that the upiu request fields are properly initialized, preventing potential issues caused by residual data from previous commands. While at it, re-use some of the common initializations for query and command upiu.

The issue is that after the trigger_dump interface is created, users can access the interface to trigger dump and call debugfs_create_files_v3_hw(). In debugfs_create_files_v3_hw(), if .debugfs_dump_dentry is NULL, the file for storing dump information is created under /sys/kernel/debug, and the memory and information cannot be released after the driver is uninstalled. Therefore, the creation of the trigger_dump interface is placed at the end of debugfs initialization.

Later in note_interrupt(), use irq_count to count hardware interrupts and irqs_unhandled to count interrupts for which no thread handler is responsible. When irq_count reaches 100000 and irqs_unhandled reaches 99000, irq will be disabled. In the performance test scenario, I/O completion hardware interrupts are continuously and quickly generated. As a result, the interrupt processing thread is cyclically called in irq_thread() and does not exit, this affects the response of the interrupt thread to the hardware interrupt and causes irqs_unhandled to grow to 99000. Finally, the irq is disabled. Therefore, default enable interrupt coalescing to reduce the generation of hardware interrupts, this helps interrupt processing threads to stop calling in irq_thread(). For interrupt coalescing, according to the actual performance test, set the count of CQ entries to 10 and the interrupt coalescing timeout period to 10us based on the actual performance test. Before and after interrupt coalescing is enabled, the 4K read/write performance is improved by about 3%, and the 256K read/write performance is basically the same.

The CFG_ICT_TIMER_STEP_TRSH register is used for sata disk to configure the step size of the timer which records the time when the disk is locked. The unit is 1us and the default step size is 150ms. If the disk is locked for more than 7 timer steps, the io to be sent to the disk will end abnormally. The current timeout is only about 1 second, it is easy to trigger IO abnormal end when the SATA hard disk returns data slowly. Adjust the timeout to 7 seconds based on ERC time of most disks.

Move the ufshcd_device_init(hba, true) call from ufshcd_async_scan() into ufshcd_init(). This patch prepares for moving both scsi_add_host() calls into ufshcd_add_scsi_host(). Calling ufshcd_device_init() from ufshcd_init() without holding hba->host_sem is safe. This is safe because hba->host_sem serializes core code and sysfs callbacks. The ufshcd_device_init() call is moved before the scsi_add_host() call and hence happens before any SCSI sysfs attributes are created. Since ufshcd_device_init() may call scsi_add_host(), only call scsi_add_host() from ufshcd_add_scsi_host() if the SCSI host has not yet been added by ufshcd_device_init().

This allows us to enable WriteBooster capability (UFSHCD_CAP_WB_EN) in a way that doesn't effect other SoCs supported in this driver. WriteBooster improves write speeds by enabling a pseudo SLC cache. Using the 'fio seqwrite' test we can achieve speeds of 945MB/s with this feature enabled (until the cache is exhausted) before dropping back to ~260MB/s (which are the speeds we see without the WriteBooster feature enabled). Assuming the UFSHCD_CAP_WB_EN capability is set by the host then WriteBooster can also be enabled and disabled via sysfs so it is possible for the system to only enable it when extra write performance is required.

This leads to a significantly cooler phone when running the upstream kernel. The exynos_ufs_post_hibern8() hook is also updated to remove the UIC_CMD_DME_HIBER_EXIT code path as this causes a hang on gs101. The code path is removed rather than re-factored as no other SoC in ufs-exynos driver sets UFSHCD_CAP_HIBERN8_WITH_CLK_GATING capability. Additionally until the previous commit the hibern8 callbacks were broken anyway as they expected a bool.

There is a possible memory leak in lpfc_sli_brdrestart_s4() (restart) and lpfc_pci_remove_one_s4() (rmmod) paths because there are no calls to lpfc_sli4_queue_unset() to kfree() the wq->pring. Fix by inserting a call to lpfc_sli4_queue_unset() in lpfc_sli_brdrestart_s4() and lpfc_sli4_hba_unset() routines. Also, add a check for the SLI_ACTIVE flag before issuing the Q_DESTROY mailbox command. If not set, then the mailbox command will obviously fail. In such cases, skip issuing the mailbox command and only execute the driver resource clean up portions of the lpfc_*q_destroy routines.

Under the erroneous assumption of successful completion, the routine proceeds to issue follow up FDMI commands, which may never complete if the HBA is in an errata state as indicated by the errored completion status. Fix by freeing FDMI cmd resources and early return when the LPFC_SLI_ACTIVE flag is not set and a LOCAL_REJECT/SLI_ABORTED or SLI_DOWN status is received.

If so, the NDLP kref count is decremented a second time in dev_loss_tmo as the final kref release. However, this can sometimes result in a reference count underflow if there is also a race to unregister with NVMe transport as well. Add a check for NVMe transport registration before decrementing the final kref. If NVMe transport is still registered, then the NVMe transport unregistration is designated as the final kref decrement.

Convert all platform drivers below drivers/scsi to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way do a few whitespace changes to make indention consistent.

The description of patch "[SCSI] implement runtime Power Management" mentions that the sg driver is skipped but not why. This patch enables runtime power management even if an instance of the sg driver is held open. Enabling runtime PM for the sg driver is safe because all interactions of the sg driver with the SCSI device pass through the block layer (blk_execute_rq_nowait()) and the block layer already supports runtime PM.

This leads to incorrectly clearing pos_unknown when the UA is for reset. Set new session only when the UA is for a new tape.
