Subject: [PATCH 4.14 018/119] ocfs2: fix panic due to ocfs2_wq is null
Date: Sun, 27 Oct 2019 21:59:55 +0100 [thread overview]
Message-ID: <20191027203305.287771867@linuxfoundation.org> (raw)
In-Reply-To: <20191027203259.948006506@linuxfoundation.org>
From: Yi Li <yilikernel@gmail.com>
commit b918c43021baaa3648de09e19a4a3dd555a45f40 upstream.
mount.ocfs2 failed when reading ocfs2 filesystem superblock encounters
an error. ocfs2_initialize_super() returns before allocating ocfs2_wq.
ocfs2_dismount_volume() triggers the following panic.
Oct 15 16:09:27 cnwarekv-205120 kernel: On-disk corruption discovered.Please run fsck.ocfs2 once the filesystem is unmounted.
