- SCSI Kernel Parameters
- ~~~~~~~~~~~~~~~~~~~~~~
- See Documentation/kernel-parameters.txt for general information on
- specifying module parameters.
- This document may not be entirely up to date and comprehensive. The command
- "modinfo -p ${modulename}" shows a current list of all parameters of a loadable
- module. Loadable modules, after being loaded into the running kernel, also
- reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
- parameters may be changed at runtime by the command
- "echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".
