Once we have a proper transport framework, we can implement a proper EXIT message instead of multiplexing o= nto trace_printk() like this. I experimented a bit with having exit() send a (much less likely to occur) non-printing character to make the second testcase work properly, but that introduces more problems than it solves. --=20 You are receiving this mail because: You are the assignee for the bug.
