RH-MergeRequest: 64: MdeModulePkg: Warn if out of flash space when writing variables

RH-Commit: [1/1] b65130800090192f47f13d67ff14f902a4f5bfb5 (osteffen/edk2)
|
||
|
|
|
||
|
|
Emit a DEBUG_WARN message if there is not enough flash space left to
|
||
|
|
write/update a variable. This condition is currently not logged
|
||
|
|
appropriately in all cases, given that full variable store can easily
|
||
|
|
render the system unbootable.
|
||
|
|
This new message helps identifying this condition.
