There are many many things to dislike about C++ -- you *can* write good clean code in C++, but almost none of the C++ code I've seen fits that description. The various side effects, and unexpected memory explosion that occurs with the "favored" C++ constructs tends to make C++ completely unsuitable for use in a kernel.
Since 1996, all of my professional programming work (for products) has been done in C++. Most of my open source work has been done in C. There should be little doubt that C++ is a much better implementation/design language than C, however, it does suffer from the interoperability concerns (and cross-compiler portability concerns) that Garrett mentions. I have not encountered issues with excessive memory consumption or slow execution.
There are plenty of people who don't know how to program in C++ or other object oriented languages. Most of these people should not be programming at all.
Zfs could have been implemented in C++, but it would not be as friendly in a kernel which is already implemented in C.
