Here is another take of my I/O topology patches. There was quite a bit of discussion at the FS & Storage workshop about the need to describe regions. Sanity prevailed, and the region code and associated complexity is now gone. There are changes in various subsystems, all depending on the block layer bits. To avoid breaking bisection I ended up creating a new block layer stacking function. Once all patches are in place we can deprecate the old one. Comments and suggestions welcome. -- Martin K.
