TYPO3 Core

there are two functions for logging: TYPO3\CMS\Core\Utility\GeneralUtility::devLog() and TYPO3\CMS\Core\Utility\GeneralUtility::sysLog()
both have a parameter $severity.

for sysLog() there are constants:

    // Severity constants used by \TYPO3\CMS\Core\Utility\GeneralUtility::sysLog()
    const SYSLOG_SEVERITY_INFO = 0;
    const SYSLOG_SEVERITY_NOTICE = 1;
    const SYSLOG_SEVERITY_WARNING = 2;
    const SYSLOG_SEVERITY_ERROR = 3;
    const SYSLOG_SEVERITY_FATAL = 4;

devLog() (should) accept the values -1 to 3 as stated in the doc-header:

* @param integer $severity Severity: 0 is info, 1 is notice, 2 is warning, 3 is fatal error, -1 is "OK" message

it would be nice to have unique values and one set of constants like:

    // Severity constants used by \TYPO3\CMS\Core\Utility\GeneralUtility::sysLog() 
        //    and \TYPO3\CMS\Core\Utility\GeneralUtility::devLog()
    const LOG_SEVERITY_OK = -1;
    const LOG_SEVERITY_INFO = 0;
    const LOG_SEVERITY_NOTICE = 1;
    const LOG_SEVERITY_WARNING = 2;
    const LOG_SEVERITY_ERROR = 3;
    const LOG_SEVERITY_FATAL = 4;
