The "accepted industry standard" for defects is 1.0; one in every thousand lines of code. Linux 3.8's 7.6 million lines of code has a defect density of .59, comparing well with 2012 (7.4 million and a .66 density) and 2011 (6.8 million and a .62 density). In general, the code quality of open source code is equivalent to that of proprietary code;
