You can't read files or execute helpers from kernel space (well, you /can/, but it is highly inadvisable). The best approach is to add a debugfs interface (see net/mac80211/debugfs*.c) that you can write to from user space via cat or the like. -- Bob Copeland %% http://bobcopeland.com/ _______________________________________________ Devel mailing list [email protected] http://lists.open80211s.org/cgi-bin/mailman/listinfo/devel
