Making HZ == USER_HZ would also solve the problem.
They were equal once.
Making them equal now would reintroduce the problem that USER_HZ was
created to resolve: some userspace programs hard-code the value, so it
cannot be changed in interfaces used by those programs.
That was the wrong solution to that particular problem. The programs
should have been fixed rather than the kernel being maimed to
accommodate their shortcomings.
