Hi,
I have written a small module that toggles the capslock LED. To demonstrate
it i want to replace the Existing keyboard module with mine. I tried
lsmod|grep "key" without any success. also checked /proc/modules. I
couldnot find any clue regarding the name of the module i need to
uninstall. So,
Hello :),
Refer this doc for user and kernel communication methods. Hope it helps :).

Hi,
I have block driver for a hot-pluggable device PCIe storage device on
kernel version 2.6.43 (which I know isn't a mainline kernel version, but
it's what I am required to build against). The driver itself is
relatively simple and implements the following block operations:
static struct

// do something 1 ;
// do something 2 ;
