No, sorry, it doesn't look so for me. They are about performance, but I'm asking about the overall project's architecture, namely about one part of it: simplicity. Particularly, what do you think about duplicating Linux page cache in the user space to have zero-copy cached I/O? Or can you suggest another architectural solution for that problem in the STGT's approach?
