I think the first thing is to bite the bullet and sort out and document the various unions in struct request for real. For example the first union has the call_single_data for the blk-mq completions, while the second one has the ipi_list that is used by the old blk-softirq code. If we get this right with a single union that contains a struct for each phase of the request we might find enough space to keep using the current way. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
