I see the following challenges with bio-chained approach. 1. partitioned device: We need to add the code which iterates over all bios and adjusts the sectors offsets. 2. dm/stacked device: We need to make major changes in dm, such as allocating cloned bios, IO splits, IO offset mappings. All of which need to iterate over chained BIOs. Overall with chained BIOs we need to add a special handling only for copy to iterate over chained BIOs and do the same thing which is being done for single BIO at present. Or am I missing something here ?
Hmm ... aren't chained bios submitted individually? See e.g. bio_chain_and_submit(). In other words, it shouldn't be necessary to add any code that iterates over bio chains. Thanks, Bart.
