  3. SCSI Kernel Parameters
  4. ======================
  5. See Documentation/admin-guide/kernel-parameters.rst for general information on
  6. specifying module parameters.
  7. This document may not be entirely up to date and comprehensive. The command
  8. ``modinfo -p ${modulename}`` shows a current list of all parameters of a loadable
  9. module. Loadable modules, after being loaded into the running kernel, also
  10. reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
  11. parameters may be changed at runtime by the command
  12. ``echo -n ${value} > /sys/module/${modulename}/parameters/${parm}``.
