[Ocfs2-devel] [PATCH 18/20] zsmalloc: Convert to migrate_folio

["Matthew Wilcox \(Oracle\) via Ocfs2-devel" <ocfs2-devel@oss.oracle.com>]

zsmalloc doesn't really use folios, but it needs to be called like this
in order to migrate an individual page.  Convert from a folio back to
a page until we decide how to handle migration better for zsmalloc.
