If anyone has any objections, please let me know. ------------------ From: Josef Bacik commit 4559b0a71749c442d34f7cfb9e72c9e58db83948 upstream. If we're trying to make a data reservation and we have to allocate a data chunk we could leak ret == 1, as do_chunk_alloc() will return 1 if it allocated a chunk. Since the end of the function is the success path just return 0.
