Subject[PATCH 0/3] acpi: Eliminate misleading erst pstore console message
Date
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
