Thank you!  Sorry I should mention, I never compiled kernel, I just upgraded from RELEASE to RELEASE.  I mentioned that newvers.sh in order to show that the upgrade appeared to be successful, because all these files that contains the version number now show the correct new version (9.2-RELEASE-p4).  Yet somehow uname shows the wrong old version (9.1-RELEASE #0).  So want to know where does uname obtained the version number.
