Darrick J. Wong	2b91b28e29	iomap: iomap_bmap should check iomap_apply return value ... Coverity caught this fairly minor bug, but we should check the return value of iomap_apply regardless.

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.

Darrick J. Wong	5157fb8f5a	iomap: move the file mapping reporting code into a separate file ... Move the file mapping reporting code (FIEMAP/FIBMAP) into a separate file so that we can group related functions in a single file instead of having a single enormous source file.
