But notice the patch is self-contained, as it fixes a current issue in the code - the risk for a lockup due to spinlock taking on atomic context. It doesn't require the panic refactor to be merged in order to achieve its goal... I agree that such issue is rare to trigger though, so definitely no hurry is needed =) Cheers, Guilherme
