Hi, So recently syzcaller ran into the big deadline/period issue (again), and I figured I should at least propose a patch that puts limits on that -- see Patch 1.
During that discussion; SCHED_OTHER servers got mentioned (also again), and I figured I should have a poke at that too. So I took some inspiration from patches Alessio Balsini send a while back and cobbled something together for that too. Included are also a bunch of patches I did for core scheduling (2-8), which I'm probably going to just merge as they're generic cleanups. They're included here because they make pick_next_task() simpler and thereby thinking about the nested pick_next_task() logic inherent in servers was less of a head-ache. (I think it can work fine without them, but its easier with them on) Anyway; after it all compiled it booted a kvm image all the way to userspace on the first run, so clearly this code isn't to be trusted at all. There's still lots of missing bits and pieces -- like changelogs and the fair server isn't configurable or hooked into the bandwidth accounting, but the foundation is there I think. Enjoy!
