This is not a problem (or should not be). It is permissible to sleep
while some interrupts are blocked; it is just not (in 4-stable)
permissible to sleep in interrupt context. The PR that I sent a few
days ago was an example of one such circumstance. Is it really the
case that in6_addmulti() can be invoked in interrupt context, and if
so, why?
