ui: change "dead" task color to gray and render dead tasks from old kernels (<4.14) thread_state.state='X' is how we currently represent dead tasks, and that is rendered with a relatively loud indigo colour by the UI. The thread query currently drops 'x' (lowercase!), but that only covers very old traces on kernels <4.14. So there are two options: (a) hide 'X' for new traces as well. (b) render all dead states, but choose a less distracting colour. I went with option (b) since I think that knowing that a thread is done can be quite useful when looking at a process with many threads. Don't have a good way of hosting images, so here's an internal screenshot: https://screenshot.googleplex.com/BThdsYv4ZoBYFcT.png Change-Id: Iba06226812cd939b08e89105e27d296ea016390b
