1The /sys/module tree consists of the following structure:
2
3What:		/sys/module/<MODULENAME>
4Description:
5		The name of the module that is in the kernel.  This
6		module name will always show up if the module is loaded as a
7		dynamic module.  If it is built directly into the kernel, it
8		will only show up if it has a version or at least one
9		parameter.
10
11		Note: The conditions of creation in the built-in case are not
12		by design and may be removed in the future.
13
14What:		/sys/module/<MODULENAME>/parameters
15Description:
16		This directory contains individual files that are each
17		individual parameters of the module that are able to be
18		changed at runtime.  See the individual module
19		documentation as to the contents of these parameters and
20		what they accomplish.
21
22		Note: The individual parameter names and values are not
23		considered stable, only the fact that they will be
24		placed in this location within sysfs.  See the
25		individual driver documentation for details as to the
26		stability of the different parameters.
27
28What:		/sys/module/<MODULENAME>/refcnt
29Description:
30		If the module is able to be unloaded from the kernel, this file
31		will contain the current reference count of the module.
32
33		Note: If the module is built into the kernel, or if the
34		CONFIG_MODULE_UNLOAD kernel configuration value is not enabled,
35		this file will not be present.
36
37What:		/sys/module/<MODULENAME>/srcversion
38Date:		Jun 2005
39Description:
40		If the module source has MODULE_VERSION, this file will contain
41		the checksum of the source code.
42
43What:		/sys/module/<MODULENAME>/version
44Date:		Jun 2005
45Description:
46		If the module source has MODULE_VERSION, this file will contain
47		the version of the source code.
