Why have several driver specific implementation if you can generalize

Please see the slides there.
If generalisation is the issue, then the solution is to define a common
API where user-space can allocate memory *in the context of* a device.
This provides a ‘give me memory I can use for this device’ request which
is what user space really wants.
Do you suggest to add a whole new common API instead of merely adding a
flag to existing one?
