* log: allow for message continuationHeinrich Schuchardt2020-10-271-0/+6
| | | | | | | | | | | | | | | | Some drivers use macro pr_cont() for continuing a message sent via printk. Hence if we want to convert printk messaging to using the logging system, we must support continuation of log messages too. As pr_cont() does not provide a message level we need a means of remembering the last log level. With the patch a pseudo log level LOGL_CONT as well as a pseudo log category LOGC_CONT are introduced. Using these results in the application of the same log level and category as in the previous log message.
