NAK the ioctl approach.
I agree it shouldn't go into mainline this way, but while the details of
the proper interface are debated, this implementation at least allows
the core function to be tested & reviewed.
People who like ioctls are just holdovers from non-Linux OS's.
Thank you for your comments.
My patches are at the experimental phase and the ioctl approach is
the provisional solution.
But I intend to continue this work with ioctl approach, if there are no
actual problems.
Cheers, Takashi
