[SCSI] Improve SCSI_LOGGING Kconfig entry
The Kconfig entry for SCSI_LOGGING refers the reader to drivers/scsi/scsi.c, but I didn't find any useful information there. There is certainly logging code in that file, but the logging types and logging levels are described in drivers/scsi/scsi_logging.h. Also, the procfs file referred to in the section is incorrect. It should be /proc/sys/dev/scsi/logging_level and not /proc/scsi/scsi. Signed-off-by: Robert Love <robert.w.love@intel.com> Signed-off-by: James Bottomley <James.Bottomley@HansenPartnership.com>

If you say N here, it may be harder to track down some types of SCSI
problems. If you say Y here your kernel will be somewhat larger, but
