- int call_usermodehelper(char * path, char ** argv, char ** envp, int wait);
- path to usermode executable
- arg vector for process
- environment for process
- wait for the application to finish and return status. when UMH_NO_WAIT don't wait at all, but you get no useful error back when the program couldn't be exec'ed. This makes it safe to call from interrupt context.
This function is the equivalent to use call_usermodehelper_setup and call_usermodehelper_exec.
