  - sched/rt: Fix race in push_rt_task Overview ======== When a CPU chooses to call push_rt_task and picks a     task to push to another CPU's runqueue then it will call find_lock_lowest_rq method which would take a     double lock on both CPUs' runqueues. If one of the locks aren't readily available, it may lead to dropping     the current runqueue lock and reacquiring both the locks at once. During this window it is possible that     the task is already migrated and is running on some other CPU. These cases are already handled. However,     if the task is migrated and has already been executed and another CPU is now trying to wake it up (ttwu)     such that it is queued again on the runqeue (on_rq is 1) and also if the task was run by the same CPU,     then the current checks will pass even though the task was migrated out and is no longer in the pushable     tasks list. Crashes ======= This bug resulted in quite a few flavors of crashes triggering kernel panics     with various crash signatures such as assert failures, page faults, null pointer dereferences, and queue     corruption errors all coming from scheduler itself.
