The balloon driver allows the Xen domain to request more memory from | |
the system to expand the domain's memory allocation, or alternatively | |
return unneeded memory to the system. | |

bool "Scrub pages before returning them to system" | |
depends on XEN_BALLOON | |
default y | |
help | |
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. Is it more | |
secure, but slightly less efficient. | |
If in doubt, say yes. |
