Hi,
I'm having trouble getting udev to create a device node in /dev/, the
init_module() code is below, the kernel loads the module fine, any
help/ideas would be much appreciated..
TIA.
Cheers.
mars char # insmod char.ko ; dmesg
char: char_init_module()
char: registered char 253,0
mars char # udevinfo -a -p /sys/module/char
looking at device '/module/char':
KERNEL=="char"
SUBSYSTEM=="module"
