From f73e98efaa10293577ae16e3e1a1fac3ab86e6d1 Mon Sep 17 00:00:00 2001 From: Jiri Bohac Date: Thu, 18 Feb 2021 12:15:47 +0100 Subject: [PATCH] pstore: Fix typo in compression option name commit 19d8e9149c27b689c6224f5c84b96a159342195a upstream. Both pstore_compress() and decompress_record() use a mistyped config option name ("PSTORE_COMPRESSION" instead of "PSTORE_COMPRESS"). As a result compression and decompression of pstore records was always disabled. Use the correct config option name.
