      "message": "sched/deadline: Add SCHED_DEADLINE inheritance logic\n\nSome method to deal with rt-mutexes and make sched_dl interact with\nthe current PI-coded is needed, raising all but trivial issues, that\nneeds (according to us) to be solved with some restructuring of\nthe pi-code (i.e., going toward a proxy execution-ish implementation).\n\nThis is under development, in the meanwhile, as a temporary solution,\nwhat this commits does is:\n\n - ensure a pi-lock owner with waiters is never throttled down. Instead,\n   when it runs out of runtime, it immediately gets replenished and it\u0027s\n   deadline is postponed;\n\n - the scheduling parameters (relative deadline and default runtime)\n   used for that replenishments --during the whole period it holds the\n   pi-lock-- are the ones of the waiting task with earliest deadline.\n\nActing this way, we provide some kind of boosting to the lock-owner,\nstill by using the existing (actually, slightly modified by the previous\ncommit) pi-architecture.\n\nWe would stress the fact that this is only a surely needed, all but\nclean solution to the problem. In the end it\u0027s only a way to re-start\ndiscussion within the community.
