- Add support for WS_EX_MDICHILD. Reordered sequence for setting WindowObject and callers styles.
- Synced mdi.c from Wine. Added support function MDI_GetId help return IDMenu.
- Thanks to GreatLord for helping.

- Setup a buffer/MDL and the correct IRP flags so that that I/O manager can handle allocation, copy, free for us.
- Setup the search pattern as an auxiliary buffer so that the I/O Mgr can track that one for us as well.
- Update to use the correct sync semantics/routines.
- Use deferred I/O completion.
- Outline TODOs and workplan for iofunc.c
svn path=/trunk/; revision=22791
- Allow async i/o access on mailslots, without a byte offset.
- Fix sync semantics just like for the other functions until now.
- Fix a potential object leak in a failure case.
- Don't call IoBuildSyncronousFsdRequest since we want to build the IRP ourselves.
- Use deferred I/O as an optimization.

svn path=/trunk/; revision=22789
- Add proper sync operation.
- Set the APC Routine/Context in the IRP instead of ignoring them.
- Dereference the event on failure.
- Set the allocated buffer as AuxiliaryBuffer so the I/O manager fres it.
svn path=/trunk/; revision=22775
- Create IopFinalizeAsynchronousIo to deal with Sync APIs working on Async file objects, which need to be waited on differently and have the IOSB copied manually.
- Update NtFlushBuffersFile to new semantics (ie, usage of the new implemented functions).
svn path=/trunk/; revision=22772
- Fix them to lock the fileobject for synch operations, use IopCleanupFailedIrp, queue the IRP in the thread's list, support aborting the I/o operation through IopAbortInterruptedIrp, and properly wait for comlpetion.
svn path=/trunk/; revision=22770
- Created our new friends: IopCleanupFailedIrp, IopAbortInterruptedIrp, IopPerformSynchronousRequest, IopLockFileObject, IopUnlockFileObject, IopQueueIrpToThread, IopUpdateOperationCount.
- What does this mean: We actually queue IRPs to their thread! We actually respect I/O transfers being interrupted/alerted! We actually respect I/O operation counts! We actually LOCK FILE OBJECTS instead of randomly using them! We now support Deferred (read: MUCH faster) I/O completion.
- First function blessed: IopDeviceFsIoControl.
- Also simplified access rights check and fixedup some formatting.
svn path=/trunk/; revision=22769
- Also use FsRtlIsTotalDeviceFailure to check if the error was a fatal device error (like a CRC error) and abandon mounting in this case as well.
svn path=/trunk/; revision=22765
- Fix a bug which was causing us to incorrectly unlock the device if it was already locked by the caller isntead of by IopMountVolume.
- When loading the file system, make sure to unlock the device object if we had locked it in IopMountVolume, as well as to re-lock it afterwards. Also handle a potential race condition due to this unloacking, in which the VPB might've become mounted behind our back, and simply return success if this happened.
svn path=/trunk/; revision=22764
- Dereference the device object in case of failure.
- Add some optimizations to quickly skip invalid raw mounting.
- Add support for VPB_RAW_MOUNT.
- Allow raw mount if this is the only device on the list.
- Make the success case go through shared exit, otherwise the device wasn't getting unlocked previously.
svn path=/trunk/; revision=22763
- Reference the device object being mounted.
- If the file system being mounted is an atachee, find its base device object too, and increase the IRP Stack for each attached FSD.
- Fix IRP parameters with this new information.
svn path=/trunk/; revision=22762
- Set the right IRP flags for a mount operation.
- Don't ignore AllowRawMount flag.
- Don't waste time passing or clearing unused flags/data on the IRP/Io Stack.
svn path=/trunk/; revision=22761
- Don't mount if the VPB is alread ymoutned or being removed
- Bugcheck the system if we failed to mount the boot partition.
svn path=/trunk/; revision=22760
- Optimize by using directly the device queue instead of allocating a structure for each FS registered.
- Hack IopMountVolume to manage this new model. Improved version coming in next patch to deal with some bugs.
svn path=/trunk/; revision=22758
- Each new change request should be queued at the end of the list, not at the head.
- Also, reference the device object for each registration, since one more object is holding a pointer to it, likewise, dereference the object on deregistration.
- IopLoadFileSystem should use the base FSD in case the device object is an attachee. Also, use IoBuildDEviceIoControlRequest to minimize the IRP setup to only a couple of lines.
svn path=/trunk/; revision=22757
- IoVerifyVolume:
- Send the IRP to the base FSD, in case the current FSD is an attachee
- Set correct flags in the IRP to notify that this is a mount operation using PAGING I/O semantics.
- Don't ignore AllowRawMount parameter.
- We want to mount the File System on *FAILURE*, not on SUCCESS!
- Add reference/dereferencing to the VPB.
svn path=/trunk/; revision=22756
- Add IoCheckQuerySetvolumeInformation to util.c from vpb.c with other similar functions
- Add the actual VPB functions in vpc.c to fs.c, and rename fs.c to volume.c, because it already contained Volume APIs, and now with VPB, even more so. It also still contains the FileSystem stuff, which is of course also generically part of "volumes".
- Delete vpb.c, rename fs.c to volume.c.
svn path=/trunk/; revision=22748
- Create \wmi directory and put wmi.c, since it's the start of a large chunk of the XP+ kernel dedicated to WMI support.
- Separate \io into \iomgr and \pnpmgr
svn path=/trunk/; revision=22747
- I/O Packet APIs improvements Part 2:
- Implement IoSetStartIoAttributes
- Obey StartIo Flags set by IoSetStartIoAttributes and change Packet functions to Windows XP/2003 semantics by supporting non-cancelable packets and deferred Start I/O calling.
svn path=/trunk/; revision=22746
- I/O Packet APIs fixes Part 1:
- Clear the current IRP before parsing the Device Queues
- Respect Cancelable parameter in IoStartNextPacket(ByKey) instead of ignoring it (acquire the cancel lock when it's requested)
- Raise IRQL to DISPATCH_LEVEL in IoStartPacket instead of expecting the caller to do it and crashing. Also only use Cancel Lock if a Cancel Function was specified.
- Actually handle the case where the IRP Was cancelled right after insert and the Cancel Routine has to be called.
svn path=/trunk/; revision=22744
- Modify IoUnregisterShudownNotification to loop both lists now.
- Used the lock in IoShutdownREgisteredDevices when looping the list, and changed it to send IRP_MJ_SHUTDOWN to the attached DO. Also fixed a memory leak where the shutdown entry wasn't being freed, and optimized the function only to initialize the event once (And simply clear it each time).
- Moved IoSynchronousInvalidateDeviceRelations to PnP
