Subject[PATCH 0/5] printk: more log flag simplification
Date
This series rearranges the log code in such a way that the LOG_CONT
and LOG_PREFIX log record flags can be eliminated entirely. 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.
