Hello, Here is v1 of a series to remove the safe buffers. They are no longer needed because messages can be stored directly into the log buffer from any context. However, the safe buffers also provided a form of recursion protection. For that reason, explicit recursion protection is also implemented for this series. This series falls in line with the printk-rework plan as presented [0] at Linux Plumbers in Lisbon 2019. This series is based on next-20210316.
