From 5a9ae68a349aa076bc8557ee2fcf865574459282 Mon Sep 17 00:00:00 2001 From: "Darrick J. Wong" Date: Fri, 19 Nov 2010 09:56:44 -0500 Subject: [PATCH] ext4: ext4_fill_super shouldn't return 0 on corruption At the start of ext4_fill_super, ret is set to -EINVAL, and any failure path out of that function returns ret. However, the generic_check_addressable clause sets ret = 0 (if it passes), which means that a subsequent failure (e.g. a group checksum error) returns 0 even though the mount should fail. This causes vfs_kern_mount in turn to think that the mount succeeded, leading to an oops. A simple fix is to avoid using ret for the generic_check_addressable check, which was last changed in commit 30ca22c70e3ef0a96ff84de69cd7e8561b416cb2. Signed-off-by: Darrick J.
