     start a usermode application
 
Synopsis

|  | int wait ); | 
 
Arguments
- sub_info
- 
     information about the subprocessa
     
- 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.
     
Description
   Runs a user-space application.  The application is started
   asynchronously if wait is not set, and runs as a child of keventd.
   (ie. it runs with full root capabilities).
