Buffer [in]Address of the block of pool memory to be freed.
Tag [in]Tag used to mark the pool block. Must be the same tag as the one used in the call to FltAllocatePoolAlignedWithTag.
None
The memory that the Buffer parameter points to must not be accessed after it is freed by FltFreePoolAlignedWithTag.
The caller of FltFreePoolAlignedWithTag can be running at IRQL DISPATCH_LEVEL if a NonPagedXxxPoolType value was specified when the memory was allocated. Otherwise, the caller must be running at IRQL <= APC_LEVEL.
