Hi,
you had such a nice userspace/kernel shared header.. and now you mix it
with kernel privates again... can you consider making this a second
header? Eg have a pure userspace clean header and a separate for-kernel
header (which #can include the user header for all I care)... that's
nicer for sure!
Greetings,
Arjan van de Ven
