[FASTFAT] Make our FAT driver PNP aware. On PNP requests it should handle, it will return STATUS_NOT_IMPLEMENTED. On the others, it will pass them to lower driver. This is the first step outside the kernel into getting IoGetRelatedTargetDevice (and so notifications) working. It doesn't work at the moment, as class2 doesn't handle PNP. [NTOSKRNL] Some fixes to IRP cancelation process: - Renamed IopRemoveThreadIrp() to IopDisassociateThreadIrp() to match Windows 2k3 - Made dead IRP global, to make its debug easier. - IopDisassociateThreadIrp(), Handle dead IRP at dispatch level, using IoCompletionLock. - IopDisassociateThreadIrp(), Use the proper error code to write the entry to logs. - IoCancelIrp(), removed non needed ASSERT, which is even not present on Windows, removed corresponding var as well. - IoCancelIrp(), fixed parameters to KeBugCheckEx() call. - IoCancelThreadIo() is pageable. - IoCancelThreadIo() under Windows isn't using given thread, but using current. Do the same here. All that stuff doesn't fix bug #5550, it comes from outside. Patch by Pierre Schweitzer, modified by me to make it compile. If it breaks anything, don't blame me! svn path=/trunk/; revision=48560

[FASTFAT] Bring in initiated work on IRPs in NTFS (and complete it). This simplifies the way IRPs and their context are handled in the driver. Only VfatDispatchRequest() is responsible of completing IRPs (if required), freeing the IRP context (if required), and queueing the IRP for later completion (if required). This allows removing duplicated code, hacks, and so on. It might help reducing IRP leaks, or memory leaks. By default, VfatDispatchRequest() will complete the IRP and delete the IRP context. In case you don't want it to complete the IRP (because you passed it down, for instance), remove the IRPCONTEXT_COMPLETE flag. See for instance: VfatDeviceControl(). In case you want to queue the IRP (you previously called: VfatQueueRequest()), call the newly introduced VfatMarkIrpContextForQueue() function that will prepare it. svn path=/trunk/; revision=67743
