_chain - chain bio completions*@bio: the target bio*@parent: the @bio's parent bio* The caller won't have a bi_end_io called when @bio completes - instead,*@parent's bi_end_io won't be called until both @parent and @bio have

submit_bio - submit a bio to the block device layer for I/O*@bio: The &struct bio which describes the I/O* submit_bio() is very similar in purpose to generic_make_request(), and* uses that function to do most of the work. Both are fairly rough
