There is no reason to call MmProbeAndLockPages for non paged pool. Instead,
you should be using MmBuildMdlForNonPagedPool to construct the MDL.
“Probe” means to ensure the VA->PA translation is valid. “Lock” means to
ensure that the VA->PA translation remains the same. For non-paged pool
this is true by the very nature of non-paged pool. Thus, using
MmProbeAndLockPages doesn’t serve any useful purpose.

Hi there ,
Can & should MmProbeAndLockPages be used for NonPagedPool memory . In
which cases ?
If a nonPagePool memory is Locked as above should it be Unlocked by
MmUnlockPages in any case ?
thanks,
dubi
