scsi: uas: Drop DID_TARGET_FAILURE use

2022-09-07T02:05:58Z

DID_TARGET_FAILURE is internal to the SCSI layer. Drivers must not use it because: 1. It's not propagated upwards, so SG IO/passthrough users will not see an error and think a command was successful. 2. There is no handling for it in scsi_decide_disposition() so it results in entering SCSI error handling. It looks like the driver wanted a hard failure so this swaps it with DID_BAD_TARGET which gives us that behavior. The error looks like it's for a case where the target did not support a TMF we wanted to use (maybe not a bad target but disappointing so close enough).

scsi: usb: Stop using the SCSI pointer

2022-02-23T02:11:07Z

Set scsi_host_template.cmd_size instead of using the SCSI pointer for storing driver-private data. Change the type of the argument of uas_add_work() from struct uas_cmd_info * into struct scsi_cmnd * because it is easier to convert a SCSI command pointer into a uas_cmd_info pointer than the other way around. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

scsi: core: Remove the 'done' argument from SCSI queuecommand_lck functions

2021-10-17T01:32:16Z

The DEF_SCSI_QCMD() macro passes the addresses of the SCSI host lock and also that of the scsi_done function to the queuecommand_lck() function implementations. Remove the 'scsi_done' argument since its address is now a constant and instead call 'scsi_done' directly from inside the queuecommand_lck() functions.

scsi: usb: Call scsi_done() directly

2021-10-17T01:31:43Z

Conditional statements are faster than indirect calls. Hence call scsi_done() directly. Link: https://lore.kernel.org/r/20211007204618.2196847-10-bvanassche@acm.org Signed-off-by: Bart Van Assche Signed-off-by: Martin K. Petersen

USB: UAS: introduce a quirk to set no_write_same

2020-12-09T19:00:26Z

UAS does not share the pessimistic assumption storage is making that devices cannot deal with WRITE_SAME. A few devices supported by UAS, are reported to not deal well with WRITE_SAME. Those need a quirk. Add it to the device that needs it. Reported-by: David C.
