Joonsoo Kim 837d026d56 mm/compaction: more trace to understand when/why compaction start/finish ...

It is not well analyzed that when/why compaction start/finish or not.
With these new tracepoints, we can know much more about start/finish
reason of compaction.  I can find following bug with these tracepoint.
