Yes, makes sense to me. So if this is the way to go, we would need two
things:
1. libata integration into the bay driver
2. The dock station driver has to inform the bay driver that an undock
event took place, right?
But you still have to deal with mounted filesystems, no matter if it a
cardbus or a cdrom. Wouldn't we need something like 'save removal'
triggered from userspace like you maybe know from 'the other' operating
system?
