Usage
int call_usermodehelper_exec(struct subprocess_info * sub_info, int wait);
Arguments
sub_info

wait
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.
Overview
Runs a user-space application. The application is started asynchronously if wait is not set, and runs as a child of system workqueues. (ie. it runs with full root capabilities and optimized affinity).
