Hi, I was wondering what the best way of doing driver to driver communication is. I'm trying to enqueue an ata-command from a completely different driver (nothing to do with storage / ata). I would just bluntly use the ata_controlcmd() function, but it would require for me to know the device_t of the drive I'm trying to access. I don't know which device_t it would be, nor do I know how to find it out. If this is a no-go... I really need some help with kobj, as I can't figure it out fully... How do you use a kobj "exported" method from another driver? Thank you in advance, Alex
