Code review comment for lp:~mshankar/epics-base/softioclogging

A few minor things which I will correct while merging:

* This code uses C++ comments in C files (which GCC accepts, but some compilers don't).
* The test code uses status values which are not related to the code being tested as test pass/fail results.
* New release note entries go at the top of the file, not the bottom.
