IOCTL_MOUNTDEV_LINK_DELETED alerts the mount manager client that a persistent name associated with it has been deleted.
Support for this IOCTL by mount manager clients is optional.

Input buffer
The mount manager places a variable-length structure of type MOUNTDEV_NAME at the beginning of the buffer at Irp->AssociatedIrp.SystemBuffer. The mount manager inserts the persistent name just assigned at the address pointed to by the Name member of this structure.
Input buffer length
Parameters.DeviceIoControl.InputBufferLength in the I/O stack location of the IRP indicates the size, in bytes, of the input buffer, which must be greater than or equal to sizeof(MOUNTDEV_NAME).
Output buffer
None.
Output buffer length
