While my minifilter is living it allocates some structures with FltAllocatePoolAlignedWithTag().
Then when it dies I would like to clean them up.
But how can I retrieve a PFLT_INSTANCE from my _FLT_REGISTRATION.PFLT_FILTER_UNLOAD_CALLBACK routine in order to call FltFreePoolAlignedWithTag?
I could record this PFLT_INSTANCE in a global variable may be, but is there a nicer way to do it?
