From 0317b728d8aee5cb065b5fbe9f99c97954bf2b4a Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 8 Jun 2021 18:13:27 +0200 Subject: [PATCH] mark pstore-blk as broken [ Upstream commit d07f3b081ee632268786601f55e1334d1f68b997 ] pstore-blk just pokes directly into the pagecache for the block device without going through the file operations for that by faking up it's own file operations that do not match the block device ones. As this breaks the control of the block layer of it's page cache, and even now just works by accident only the best thing is to just disable this driver.
