[ros-dev] [ros-diffs] [fireball] 53596: [NTOS/CONFIG] - Remove unnecessary assignments. Spotted by PVS and Dmitry Chapyshev. This may change the behaviour of that codepath, so test results are going to be observed.

[Alex Ionescu]

Uhhhh...

Am I really the *only* one who sees a problem here?

ChildList = &Kcb->ValueCache;
-    ChildList = (PCACHED_CHILD_LIST)&KeyNode->ValueList;

Best regards,
Alex Ionescu
