Get IRP requestor module function for kernel driver

Hello! I have a kernel driver, i need a function, which would return module full file name of IRP requestor module. Something like IoGetRequestorProcess(Irp), but module full file name instead of process. I need this because i request my driver from injected dll, and i need get this dll full name from kernel driver. Kernel driver is for Windows XP, Vista, 7, 8. Thanks!
