Not really, as I've explained, I want to do all these stuff in kernel space. More specifically, I want to write a newbie kernel module. In this module, I'll do something with a raw block device (with no filesystem). For example, I want to do block I/O operations on ramdisk, and I want to set the block size of ramdisk to whatever value I want (power of 2 of course).
Pick up a copy of Linux Device Drivers by Rubini & Corbet (O'Reilly, 2001) and start with the example ramdisk block driver in chapter 12.
