+RH-MergeRequest: 64: MdeModulePkg: Warn if out of flash space when writing variables
+RH-Jira: RHEL-43442
+RH-Acked-by: Gerd Hoffmann <None>
+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.
