[PATCH] zfcp: fix infinite iteration on ERP ready list

From: Jens Remus zfcp_erp_adapter_reopen() schedules blocking of all of the adapter's rports via zfcp_scsi_schedule_rports_block() and enqueues a reopen adapter ERP action via zfcp_erp_action_enqueue(). Both are separately processed asynchronously and concurrently.

[PATCH v2 10/10] scsi: ufs: Add clock ungating to a separate workqueue

From: Vijay Viswanath UFS driver can receive a request during memory reclaim by kswapd. So when ufs driver puts the ungate work in queue, and if there are no idle workers, kthreadd is invoked to create a new kworker. Since kswapd task holds a mutex which kthreadd also

[PATCH v2 02/10] scsi: ufs-qcom: Enable UFSHCD_QUIRK_BROKEN_PWR_MODE_CHANGE quirk

[PATCH v2 01/10] scsi: ufs: Allowing power mode change

From: Yaniv Gardi Due to M-PHY issues, moving from HS to any other mode or gear or even Hibern8 may cause some un-predicted behavior of the device. This patch adds provides a quirk to address that. Signed-off-by: Yaniv Gardi Signed-off-by: Subhash

[PATCH v2 06/10] scsi: ufs: add reference counting for scsi block requests

From: Subhash Jadavani Currently we call the scsi_block_requests()/scsi_unblock_requests() whenever we want to block/unblock scsi requests but as there is no reference counting, nesting of these calls could leave us in undesired state sometime. Consider following call

[PATCH v2 04/10] scsi: ufs: fix exception event handling

From: Maya Erez The device can set the exception event bit in one of the response UPIU, for example to notify the need for urgent BKOPs operation. In such a case the host driver calls ufshcd_exception_event_handler to handle this notification. When trying to check the

[PATCH v2 08/10] scsi: ufs: make sure all interrupts are processed

From: Venkat Gopalakrishnan As multiple requests are submitted to the ufs host controller in parallel there could be instances where the command completion interrupt arrives later for a request that is already processed earlier as the corresponding doorbell was cleared

[PATCH v2 05/10] scsi: ufshcd: fix possible unclocked register access

From: Subhash Jadavani vendor specific setup_clocks ops may depend on clocks managed by ufshcd driver so if the vendor specific setup_clocks callback is called when the required clocks are turned off, it results into unclocked register access. This change make sure that

[PATCH v2 07/10] scsi: ufs-qcom: remove broken hci version quirk

From: Subhash Jadavani UFSHCD_QUIRK_BROKEN_UFS_HCI_VERSION is only applicable for QCOM UFS host controller version 2.x.y and this has been fixed from version 3.x.y onwards, hence this change removes this quirk for version 3.x.y onwards. Signed-off-by: Subhash Jadavani

[PATCH v2 03/10] scsi: ufs: Add LCC quirk for host and device

LCC (Line Control Command) is being used for communication between UFS host and UFS device. But some hosts might have the issue with issuing the LCC commands to UFS device and in this case LCC could be explicitly disabled. But there could be a need where we don't want to disable the LCC on both

[PATCH] scsi: megaraid: silence a static checker bug

If we had more than 32 megaraid cards then it would cause memory corruption. That's not likely, of course, but it's handy to enforce it and make the static checker happy. Signed-off-by: Dan Carpenter diff --git a/drivers/scsi/megaraid.c b/drivers/scsi/megaraid.c index
