Hans Petter Selasky 714ed5b27b Fix for deadlock situation in the LinuxKPI's RCU synchronize API. ... Deadlock condition: The return value of TDQ_LOCKPTR(td) is the same for two threads. 1) The first thread signals a wakeup while keeping the rcu_read_lock(). This invokes sched_add() which in turn will try to lock TDQ_LOCK(). 2) The second thread is calling synchronize_rcu() calling mi_switch() over and over again trying to yield(). This prevents the first thread from running and releasing the RCU reader lock. Solution: Release the thread lock while yielding to allow other threads to acquire the lock pointed to by TDQ_LOCKPTR(td).
