Arnaldo Carvalho de Melo e519bd9a07 perf trace: Do not print interrupted syscalls when using --duration ... With multiple threads, e.g. a system wide trace session, and one syscall is midway in a thread and another thread starts another syscall we must print the start of the interrupted syscall followed by ..., but that can't be done that way when we use the --duration filter, as we have to wait for the syscall exit to calculate the duration and decide if it should be filtered, so we have to disable the interrupted logic and only print at syscall exit, duh.
