Help text

Scrub pages before returning them to the system for reuse by other domains. This makes sure that any confidential data is not accidentally visible to other domains. It is more secure, but slightly less efficient. This can be controlled with xen_scrub_pages=0 parameter and /sys/devices/system/xen_memory/xen_memory0/scrub_pages. This option only sets the default value.

If in doubt, say yes.
