This driver iterates over all paged lookaside lists, nonpaged lookaside lists and resources and prints for each the address and whether it is located in a driver or in the pool. If structure is in a driver, driver name will be printed. If structure is in the pool, pool tag will be printed for lookasides but not for resources, since tag is not a part of the ERESOURCE structure and difficult to retrieve in Windows10 RS5+. Before RS5 pool parsing is possible to get tag and size information about resources and lookasides.
