What is a VCHR device? You mention it quite a lot in the commit messages, but I have no idea what it is, unless it's like a acronym cross combining VHS and VCR. :)
RAW disk I/O is an example.
But, what is it? Raw disk I/O is an example of many things unrelated to VCHR, so telling me an example of something still doesn't tell me what a VCHR device is.
I am surprised, do you really not know? The AIO/LIO code was primarily included
to
support optimized database operations, and I/O is often done to raw disks.
