/sys/module/MODULENAME is not created unconditionally. This can be confusing so document the current conditions. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Rob Landley <rob@landley.net> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

What: /sys/module
|
|
Description:
|
|
The /sys/module tree consists of the following structure:
|
|
|
|
/sys/module/MODULENAME
|
|
The name of the module that is in the kernel. This
|
|
module name will always show up if the module is loaded as a
|
|
dynamic module. If it is built directly into the kernel, it
|
|
will only show up if it has a version or at least one
|
|
parameter.
|
|
|
|
Note: The conditions of creation in the built-in case are not
|
|
by design and may be removed in the future.
|
|
|
|
/sys/module/MODULENAME/parameters
|
|
This directory contains individual files that are each
|
|
individual parameters of the module that are able to be
|
|
changed at runtime. See the individual module
|
|
documentation as to the contents of these parameters and
|
|
what they accomplish.
|
|
|
|
Note: The individual parameter names and values are not
|
|
considered stable, only the fact that they will be
|
|
placed in this location within sysfs. See the
|
|
individual driver documentation for details as to the
|
|
stability of the different parameters.
|
|
|
|
/sys/module/MODULENAME/refcnt
|
|
If the module is able to be unloaded from the kernel, this file
|
|
will contain the current reference count of the module.
|
|
|
|
Note: If the module is built into the kernel, or if the
|
|
CONFIG_MODULE_UNLOAD kernel configuration value is not enabled,
|
|
this file will not be present.
