Christoph Hellwig ae5535efd8 iomap: don't chain bios ... Back in the days when a single bio could only be filled to the hardware limits, and we scheduled a work item for each bio completion, chaining multiple bios for a single ioend made a lot of sense to reduce the number of completions. But these days bios can be filled until we reach the number of vectors or total size limit, which means we can always fit at least 1 megabyte worth of data in the worst case, but usually a lot more due to large folios. The only thing bio chaining is buying us now is to reduce the size of the allocation from an ioend with an embedded bio into a plain bio, which is a 52 bytes differences on 64-bit systems. This is not worth the added complexity, so remove the bio chaining and only use the bio embedded into the ioend. This will help to simplify further changes to the iomap writeback code.
