Rather than having hundreds of variations of call_usermodehelper for various pieces of usermode state which could be set up, split the info allocation and initialization from the actual process execution. This means the general pattern becomes: info = call_usermodehelper_setup(path, argv, envp); /* basic state */ call_usermodehelper_<SET EXTRA STATE>(info, stuff...); /* extra state */ call_usermodehelper_exec(info, wait); /* run process and free info */ This patch introduces wrappers for all the existing calling styles for call_usermodehelper_*, but folds their implementations into one.
