在对KeRemoveQueue的调用中将WaitMode指定为KernelMode会阻止调用线程的内核堆栈被交换,并阻止在 APC) (传递用户模式异步过程调用。 它不会阻止内核模式 APC 的传递,例如当线程从 IRQL PASSIVE_LEVEL调用KeRemoveQueue时,I/O 管理器用来完成 IRP 的 APC。 此类内核模式 APC 的传递不会阻止调用线程等待队列对象,也不...

() from within TransporterFacade.cpp seem to be guarded with a check that the Receiver is actually in the cond_wait_queue(). The calls from Ndbif.cpp (and anywhere else) should probably also check this. If the Receiver is not in the cond_wait_queue then we shouldn't attempt to ...
