The patch titled
Subject: zsmalloc: use class->pages_per_zspage
has been removed from the -mm tree. Its filename was
zsmalloc-use-class-pages_per_zspage.patch

------------------------------------------------------
From: Minchan Kim <minchan@xxxxxxxxxx>
Subject: zsmalloc: use class->pages_per_zspage
There is no need to recalcurate pages_per_zspage in runtime. Just use
class->pages_per_zspage to avoid unnecessary runtime overhead.
