...
+static int btrfs_get_blocks_direct_write(struct extent_map **map,
+ struct buffer_head *bh_result,
+ struct inode *inode,
+ struct btrfs_dio_data *dio_data,
+ u64 start, u64 len)
+{
+ int ret = 0;
That initialization value is not needed, since ret is always overwritten
two lines later.
+ struct extent_map *em;
+
+ ret = btrfs_get_extent_map_write(map, bh_result, inode,
+ start, len);
+ if (ret < 0)
+ return ret;
+ em = *map;
