Those patches replace the previous Query Request and NOP patches: [PATCH 1/8] scsi: ufs: add support for query [PATCH 7/8] scsi: ufs: Set fDeviceInit flag to initiate device initialization [PATCH 8/8] scsi: ufs: Fix the response UPIU length setting And depends on: [PATCH 2/8] scsi: ufs: wrap the i/o access operations [PATCH 3/8] scsi: ufs: amend interrupt configuration [PATCH 4/8] scsi: ufs: remove version check before IS reg clear [PATCH 5/8] scsi: ufs: rework link start-up process Sending the query request via the SCSI vendor specific command can cause a deadlock in case the SCSI command queue is blocked and we would like to send a query request (for example fDeviceInit in case of re-initialization). In addition, usage of a vendor specific SCSI command for UFS can cause future conflicts if this vendor specific command will be allocated for a different usage. The below patches allocate an internal tag for NOP and query requests and do not involve the SCSI layer in UFS specific requests transfers. This design also resolves the possible deadlock mentioned above.
