Should happen at most once unless you play games with your torrc and HUPing. I think we should keep this as notice (maybe even warn, but we don't want it to be too scary since it may not indicate a problem). Yes keep this one. > > `Scheduler type KIST has been disabled by the consensus or no kernel support` which gets called every time we call `select_scheduler()`, have KIST in `Schedulers`, but can't use it. I think this should be moved to info or removed. This one I propose we keep it notice but print _once_ and after that we do not. However, in the case of no kernel support, this is detected at runtime and we do log notice about it when detected so we don't need it. Thus the only way to transition out of KIST while having KIST enabled in Schedulers then is through the consensus. We should log notice that it happened but only once, not everytime we get a consensus. And if we ever transition back to KIST after a while, we'll get the "Scheduler type %s has been enabled" so we'll be back on track. > > I will gladly take care of this.
