Log message:
	Commit ID 46a75dedb4f6aa815a804f27cafbd3fd16a62011 consolidated code from the
	various dmeventd plug-ins into a new function called 'dmeventd_lvm2_command',
	but the new function did not strip off the "_mlog" extentions that the
	mirror plug-in had been doing.  This created bug 794904 - failure to replace
	devices in a redundant log.
	
	The test suite did catch this scenario because it performs repair tests (mainly)
	through the CLI and not dmeventd.  It's also not easy to test because the test
	itself will hang if the bug is encountered.
