class SysfsPlugin(base.Plugin):
	"""
	`sysfs`::
	
	Sets various `sysfs` settings specified by the plug-in options.
	+
	The syntax is `_name_=_value_`, where
	`_name_` is the `sysfs` path to use and `_value_` is
	the value to write. The `sysfs` path supports the shell-style
	wildcard characters (see `man 7 glob` for additional detail).
	+
	Use this plugin in case you need to change some settings that are
	not covered by other plug-ins. Prefer specific plug-ins if they
	cover the required settings.
	+
	.Ignore corrected errors and associated scans that cause latency spikes
