commit eb384b55 upstream. This is the same as the fix from commit Btrfs: fix bad extent logging but for O_DIRECT. I missed this when I fixed the problem originally, we were still using the em for the orig_start and orig_block_len, which would be the merged extent. We need to use the actual extent from the on disk file extent item, which we have to lookup to make sure it's ok to nocow anyway so just pass in some pointers to hold this info.
