Actually, there are spots where the nucleus forces do_exit() over the caller, and specifically, when we zap a shadow from the Xenomai context, then perform a tail scheduling for this zombie over the incoming Linux context. In such situation, the user-space would not even be informed of what's been going on, so the cleanup routine would be useless. -- Philippe. _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
