On systems that have a valid ACPI ERST table, if the pstore.backend kernel parameter selects a specific facility other than erst, then during boot the following console message is displayed:
ERST: Could not register with persistent store
This message makes it seem that something has gone wrong. In fact the same message is used when you want ERST to be used by pstore and some real error precludes registration.
The primary purpose of this 3 patch set is to avoid displaying this console error message when another facility is explicitly selected as the backend for pstore. Details are in the individual patches.
Lenny Szubowicz (3): pstore: Return unique error if backend registration excluded by kernel param acpi: Eliminate console msg if pstore.backend excludes ERST efivars: If pstore_register fails, free unneeded pstore buffer
