Goldwyn Rodrigues c039b99792 iomap: use a srcmap for a read-modify-write I/O ... The srcmap is used to identify where the read is to be performed from. It is passed to ->iomap_begin, which can fill it in if we need to read data for partially written blocks from a different location than the write target. The srcmap is only supported for buffered writes so far.
