The ip6_sf_list has been protected by mca_lock(spin_lock) so that the critical section is atomic context. In order to switch this context, changing locking is needed. The ip6_sf_list actually already protected by RTNL So if it's converted to use RCU, its control path context can be switched to sleepable. But It doesn't remove mca_lock yet because ifmcaddr6 isn't converted to RCU yet. So, It's not fully converted to the sleepable context.
