    ip6_del_rt(ifp->rt)

after returning from the ipv6_ifa_notify and enabling BH-s

  inet6_ifa_finish_destroy(ifp)

3. invocation:
  Same as 2. invocation, endless invocation of callback.

16 years agorfkill: ignore errors from rfkill_toggle_radio in rfkill_add_switch
Henrique de Moraes Holschuh [Thu, 3 Jul 2008 16:14:57 +0000 (13:14 -0300)]
rfkill: ignore errors from rfkill_toggle_radio in rfkill_add_switch

rfkill_add_switch() calls rfkill_toggle_radio() to set the state of a
recently registered rfkill class to the current global state [for that
rfkill->type].

The rfkill_toggle_radio() call is going to error out if the hardware is
RFKILL_STATE_HARD_BLOCKED, and the global state is RFKILL_STATE_UNBLOCKED.

That is a quite normal situation which I missed to account for.  As things
stand, the error return from rfkill_toggle_radio ends up causing
rfkill_register to bail out with an error (de-registering the new switch in
the process), which is Not Nice.

Change rfkill_add_switch() to not return errors because of a failed call to
rfkill_toggle_radio().  We can go back to returning errors again (if that's
indeed the right thing to do) if we define the exact error codes the
rfkill->toggle_radio callbacks are to return in each situation, so that we
can ignore the right ones only.
