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).
If nobody could answer this question, what about another one? Is there a system call or a kernel interface that would allow me to write a
Can you use read, write and seek system calls? -- vda
