Help text

This keeps track of what call chain is the owner of a page, may help to find bare alloc_page(s) leaks. Even if you include this feature on your build, it is disabled in default. You should pass "page_owner=on" to boot parameter in order to enable it. Eats a fair amount of memory if enabled. See tools/mm/page_owner_sort.c for user-space helper.

If unsure, say N.
