Arnaldo Carvalho de Melo 3803a22931 perf trace: Put the per-syscall entry/exit prog_array BPF map infrastructure in place ... I.e. look for "syscalls_sys_enter" and "syscalls_sys_exit" BPF maps of type PROG_ARRAY and populate it with the handlers as specified per syscall, for now only 'open' is wiring it to something, in time all syscalls that need to copy arguments entering a syscall or returning from one will set these to the right handlers, reusing when possible pre-existing ones. Next step is to use bpf_tail_call() into that.
