I don't have that kind of data, so any numbers that I might say are based solely on my own experience and my circle of friends working in tech. That said, a friend of mine hit an EXT4 resize bug (https://www.spinics.net/lists/linux-ext4/msg86163.html https://www.spinics.net/lists/linux-ext4/msg86163.html) the other day. IMHO regressions on fairly common features should be captured by unit tests and should never get their way to production.
