@Bhaumik10 , thanks for this work. For now, we're going to refrain from using the controller runtime logging adaptor to keep the scope of the parent task more constrained. As such, we'll continue using the klog logging funcs directly in the controllers. Please take a look at this PR, which is already merged, and make changes accordingly for this one. Thanks!
