Re: [PATCH 8/9] rfkill: Userspace control for airplane mode

Hi Joa Paulo,

Provide an interface for the airplane-mode indicator be controlled from
userspace. User has to first acquire the control through
RFKILL_OP_AIRPLANE_MODE_ACQUIRE and keep the fd open for the whole time
it wants to be in control of the indicator. Closing the fd or using
RFKILL_OP_AIRPLANE_MODE_RELEASE restores the default policy.

To change state of the indicator, the RFKILL_OP_AIRPLANE_MODE_CHANGE
operation is used, passing the value on "struct rfkill_event.soft". If
the caller has not acquired the airplane-mode control beforehand, the
operation fails.

as explained in an earlier response, the concept Airplane Mode seems to be imposing policy into the kernel. Do we really want have this as a kernel exposed API.

Regards

Marcel
