Are calls to ExAllocateFromPagedLookasideList and ExFreeToPagedLookasideList
synchronized (against the LookasideList), or do I need to put my own mutual
exclusions into the bodies of my Allocate and Free functions?
Keith
They are synchronized in the sense that concurrent calls to these
functions will not corrupt the data structure. Lookaside lists are
designed to be lock free from the perspective of the list user.

Yes they are. They are macros, look at their implementation.
