Hi all. Here is my current patch queue. Taken together, the patches implement the separation of low level block i/o into a separate file, switch from using swap_map_pages to extents stores prior to the 'header' page and implement fully asynchronous (rather than batched I/O). I have only run it under VMware so far, but would estimate a doubling in speed due to the async i/o. Looking at Jiri's patches, there is definitely some overlap, but more in terms of lines in the code than direction of effort (with the exception of separating swap out). He has covered areas for improvement that I was going to do, just not yet. Jiri, unless you object, I'm going to seek to apply your patches on top of what I've done. Does that sound okay?
