Is the future MmProbeAndLockPages() guarranted to succeed if the memory has been locked before?

In my program, we want to MmProbeAndLockPages() a certain amount of memory
in powerup, but in the runtime, we may only need a part of pre-locked memory
to do DMA operation. I am wondering whether the future MmProbeAndLockPages()
can be ensured to work if the memory has already been locked. I think it
does, but I just want to make sure.

Thanks,
