Hi all,
I've started this as a new thread to prevent polluting the discussions of the
media controller as a concept.
First of all, I have no doubt that everything that you can do with an ioctl,
you can also do with sysfs and vice versa. That's not the problem here.
The problem is deciding which approach is the best.
Is it really a good idea to create a dependency to some virtual file
system which may go away in future?
From time to time some of those seem to go away, for example devfs.
Is it really unavoidable to have something in sysfs, something which is
really not possible with ioctls?
And do you really want to depend on sysfs developers?
