config SCSI_LOGGING
    bool "SCSI logging facility"
    depends on SCSI
    ---help---
      This turns on a logging facility that can be used to debug a number
      of SCSI related problems.
 
      If you say Y here, no logging output will appear by default, but you
      can enable logging by saying Y to "/proc file system support" and
      "Sysctl support" below and executing the command
 
      echo <bitmask> > /proc/sys/dev/scsi/logging_level
 
      where <bitmask> is a four byte value representing the logging type
      and logging level for each type of logging selected.
 
      There are a number of logging types and you can find them in the
      source at <file:drivers/scsi/scsi_logging.h>. The logging levels
      are also described in that file and they determine the verbosity of
      the logging for each logging type.
 
      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
      there should be no noticeable performance impact as long as you have
      logging turned off.

/*
 * Note - the initial logging level can be set here to log events at boot time.
 * After the system is up, you may enable logging via the /proc interface.
