Jim Harris 2edc652913 reduce: save num_io_units and chunk_is_compressed to req object ... When a chunk cannot be compressed enough to save one I/O unit, we will just write the uncompressed data to disk. In this case, we want the helper routine to use the decomp_buf instead of the comp_buf. To facilitate that, save some information in the request object on the number of io_units to be read from or written to disk, and whether the data is compressed or not. We could easily deduce if the data is compressed based on the number of io_units but saving it in the structure will save a few instructions and simplify the code a bit.
