Subject: [PATCH] hibernate: Disable in a signed modules environment
|
|
|
|
There is currently no way to verify the resume image when returning
|
|
from hibernate. This might compromise the signed modules trust model,
|
|
so until we can work with signed hibernate images we disable it in
|
|
a secure modules environment.
