In chunk_aligned_read() we are adding data_offset before calling is_badblock. But is_badblock also adds data_offset, so that is bad. So move the addition of data_offset to after the call to is_badblock. This bug was introduced by commit 31c176ecdf3563140e639 md/raid5: avoid reading from known bad blocks. which first appeared in 3.0. So that patch is suitable for any -stable kernel from 3.0.y onwards. However it will need minor revision for most of those (as the comment didn't appear until recently).
