From: Chen Haonan <[email protected]> persistent_ram_zap() is used to clear relevant log messages in dmesg, but in other cases it is not needed.In particular, in console and pmsg, it will cause that after we perform a delete operation, the next time the system is reset, we will only see the logs after performing the delete operation.
