So I think a lot of the problems with this series is that SRCU is introduced too late. We are debating things in patch 6 that are irrelevant by patch 12. I will rework the series so that the changes come in the following order: 1. provide an atomic console_is_enabled() 2. convert the list to SRCU 3. move all iterators from console_lock()/console_trylock() to SRCU Step 3 may result in console_lock()/console_trylock() calls disappearing or relocating to where they are needed for non-list-synchronization purposes.
