Open-code scsi_print_result in sd.c, and cleanup logging to not print duplicate informations. Also remove the call to scsi_show_result() in ufshcd.c to be consistent with other callers of scsi_execute(). With that we can remove scsi_show_result in constants.c Signed-off-by: NHannes Reinecke <hare@suse.de> Reviewed-by: NRobert Elliott <elliott@hp.com> Signed-off-by: NChristoph Hellwig <hch@lst.de>

print_opcode_name() was only ever called with a '0' argument from LLDDs and ULDs which were _not_ supporting variable length CDBs, so the 'if' clause was never triggered. Instead we should be using the last argument to specify the cdb length to avoid accidental overflow when reading the cdb buffer.

Further to a January 2013 thread titled: "[PATCH] SG_SCSI_RESET ioctl should only perform requested operation" by Jeremy Linton a patch (v3) is presented that expands the existing ioctl to include "no_escalate" versions to the existing resets. This requires no changes to SCSI low level drivers (LLDs); it adds several more finely tuned reset options to the user space. For example: /* This call remains the same, with the same escalating semantics * if the device (LU) reset fail. That is: on failure to try a * target reset and if that fails, try a bus reset, and if that fails * try a host (i.e. LLD) reset. */ val = SG_SCSI_RESET_DEVICE; res = ioctl(<sg_or_block_fd>, SG_SCSI_RESET, &val); /* What follows is a new option introduced by this patch series. Only * a device reset is attempted. If that fails then an appropriate * error code is provided. N.B. There is no reset escalation. */ val = SG_SCSI_RESET_DEVICE | SG_SCSI_RESET_NO_ESCALATE; res = ioctl(<sg_or_block_fd>, SG_SCSI_RESET, &val); Signed-off-by: NDouglas Gilbert <dgilbert@interlog.com> Reviewed-by: NJeremy Linton <jlinton@tributary.com> Reviewed-by: NHannes Reinecke <hare@suse.de> Signed-off-by: NChristoph Hellwig <hch@lst.de>

This patch fixes an issue with multipath ipr SAS devices which require a start unit command to be issued following an adapter reset. Without this patch, paths get marked failed following an adapter reset and since the error handler never gets invoked to issue the start unit, the paths are never recovered.

Multipath devices using the TUR path checker need to see the sense code for a failed TUR command in their device handler. Since commit 14216561 we always return success for mid layer issued TUR commands before calling the device handler, which stopped the TUR path checker from working. Move the call to the device handler check sense method before the early return for TUR commands to give the device handler a chance to intercept them.
