Tejun Heo c3c94c5a2f [SCSI] sd: implement START/STOP management
Implement SBC START/STOP management.  sdev->mange_start_stop is added.
When it's set to one, sd STOPs the device on suspend and shutdown and
STARTs it on resume.  sdev->manage_start_stop defaults is in sdev
instead of scsi_disk cdev to allow ->slave_config() override the
default configuration but is exported under scsi_disk sysfs node as
sdev->allow_restart is.

When manage_start_stop is zero (the default value), this patch doesn't
introduce any behavior change.

Martin K. Petersen e73aec8247 [SCSI] sd: make printing use a common prefix
Make SCSI disk printing more consistent:

 - Define sd_printk(), sd_print_sense_hdr() and sd_print_result()

 - Move relevant header bits into sd.h

 - Remove all the legacy disk_name passing and use scsi_disk pointers
   where possible

 - Switch printk() lines to the new sd_ functions so that output is
   consistent
