When a thread exits, it finds the first non-zero value on the stack, and from that calculates the max stack excursion. See check_stack_usage() called from do_exit(). -Eric _______________________________________________ Fedora-kernel-list mailing list Fedora-kernel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-kernel-list
