Andrew, could you please squash the following diff in? I intentionally did not state the name of the new APIs to avoid needing to update the docs with similar changes in the future: diff --git a/Documentation/mm/zsmalloc.rst b/Documentation/mm/zsmalloc.rst index 76902835e68e9..d2bbecd78e146 100644 --- a/Documentation/mm/zsmalloc.rst +++ b/Documentation/mm/zsmalloc.rst @@ -27,9 +27,8 @@ Instead, it returns an opaque handle (unsigned long) which encodes actual location of the allocated object.
