10 Following is an overview of available syscall probes and convenience
11 variables they offer. By default, each syscall probe has name and
12 argstr convenience variables, which are not included in the overview in
13 order to keep it short. Non dwarf-based nd_syscall probes are supposed
14 to have the same convenience variables.
