Annotated Snippet

The /sys/module tree consists of the following structure:

What:		/sys/module/<MODULENAME>
Description:
		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.

What:		/sys/module/<MODULENAME>/parameters
Description:
		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.

What:		/sys/module/<MODULENAME>/refcnt
Description:
		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.

What:		/sys/module/<MODULENAME>/srcversion
Date:		Jun 2005
Description:
		If the module source has MODULE_VERSION, this file will contain
		the checksum of the source code.

What:		/sys/module/<MODULENAME>/version
Date:		Jun 2005
Description:
		If the module source has MODULE_VERSION, this file will contain
		the version of the source code.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
