Migrate page will directly call the btrfs btree writepage function, which isn't actually allowed.
Our writepage assumes that you have locked the extent_buffer and flagged the block as written. Without doing these steps, we can corrupt metadata blocks.
A later commit will remove the btree writepage function since it is really only safely used internally by btrfs. We use writepages for everything else.
