As the discussion in the list, the zsmalloc introduce some problems
around pages because its pages are unmovable.

These patches introduced page move function to zsmalloc.  And they also
add interface to struct page.

Hui Zhu (3):
page: add new flags "PG_movable" and add interfaces to control these pages
zsmalloc: mark its page "PG_movable"
zram: make create "__GFP_MOVABLE" pool
