Subject: [PATCH] Bug 700153: restore: always check available stack
|
|
|
5e8686 |
|
|
|
5e8686 |
Previously, we were checking there was enough stack space available when the
|
|
|
5e8686 |
restore operation required a device change, but since we have to use
|
|
|
5e8686 |
Postscript to reset the userparams (ick!), we need the stack check even when
|
|
|
5e8686 |
not changing the device.
