Hi, I was tracing some simple programs and came up with a list of
"sys_unknown" tracepoints. This may or may not help for developers to
see what they are.

sys_unknown id = 11 => exec_ve
sys_unknown id = 119 => sigreturn
sys_unknown id = 120 => clone
sys_unknown id = 184 => capget
sys_unknown id = 185 => capset
sys_unknown id = 194 => ftruncate (?) confirm please
sys_unknown id = 243 => set_thread_area (?) confirm please
sys_unknown id = 250 => fadvise (?) confirm please
sys_unknown id = 314 => sync_file_range (?) confirm please
