The tracepoint event kvm_userspace_exit uses string snippet the C compiler concatenates to a big string, e.g. "KVM_EXIT_" "UNKNOWN". The parser of the data must do the same and join successive strings.
print fmt: "reason %s (%d)", … __print_symbolic(REC->reason, { 0, "KVM_EXIT_" "UNKNOWN" }, { 1, "KVM_EXIT_" "EXCEPTION" } …
