Commit 345c0dbf ("ext4: protect journal inode's blocks using block_validity") failed to add an exception for the journal inode in ext4_check_blockref(), which is the function used by ext4_get_branch() for indirect blocks. This caused attempts to read from the ext3-style journals to fail with: [ 848.968550] EXT4-fs error (device sdb7): ext4_get_branch:171: inode #8: block 30343695: comm jbd2/sdb7-8: invalid block Fix this by adding the missing exception check. Fixes: 345c0dbf ("ext4: protect journal inode's blocks using block_validity") Reported-by: NArthur Marsh <arthur.marsh@internode.on.net> Signed-off-by: NTheodore Ts'o <tytso@mit.edu>
