The result should be considerably easier to understand than before. It builds on another recently-posted series of patches: https://lkml.org/lkml/2014/7/17/363 The first patch exploits the fact that LOG_CONT and LOG_NEWLINE are inverses, and uses LOG_NEWLINE (or its negation) anywhere LOG_CONT is used. As a result, LOG_CONT is no longer needed, so it's eliminated. The next three patches together eliminate LOG_PREFIX. The effect of LOG_PREFIX is to complete the previous log entry before recording a new one. Patch 2 arranges to do this directly, marking the previous log record with LOG_NEWLINE whenever a new record is presented with LOG_PREFIX set. Patch 3 stops saving LOG_PREFIX in any log records, and patch 4 finally gets rid of LOG_PREFIX. The last patch is just some cleanup of the code now that it's gone through this transformation. -Alex This series is available here: http://git.linaro.org/landing-teams/working/broadcom/kernel.git Branch review/more-printk-flags It is based on branch review/printk-flags-v2 in that same repository.
