This sounds like a dubious way of doing things. It only seems superficially attractive because you place a high cost on programming inside the kernel. But in fact in-kernel programming not all that hard. It's harder to support the loopback into user space properly. Any such "filter" or "shim" requires very careful engineering. Just look at the fiasco of Machek's NBD to appreciate what you're handwaving away. So, my personal suggestion is to reconsider your approach. -- Pete ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
