Since you're dropping this and relying on the lock being taken higher up callstack, can we add a lockdep assertion that we do actually hold the devices_lock, please?Will do!
I spoke too soon; the point of this change was to remove the dependency on the arm_smmu_domain, piping the devices_lock would defeat this. In fact, this section is really depending on the iommu group lock not the devices_lock. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
