No tests?

Parent article: Development statistics for the 7.1 kernel

Out of curiosity I looked at one of the patches and the code makes sense - what strikes me though is the lack of tests. I might be spoiled by $WORK where test coverage is measured and enforced, but I still find is strange that a bugfix goes into the kernel without some kind of test triggering the fixed fault and showing that the fix is indeed a fix (and hopefully ensuring that the bug doesn't come back).
