From mboxrd@z Thu Jan 1 00:00:00 1970 From: Matthew Wilcox (Oracle) Date: Mon, 6 Jun 2022 21:40:48 +0100 Subject: [Cluster-devel] [PATCH 18/20] zsmalloc: Convert to migrate_folio In-Reply-To: <20220606204050.2625949-1-willy@infradead.org> References: <20220606204050.2625949-1-willy@infradead.org> Message-ID: <20220606204050.2625949-19-willy@infradead.org> List-Id: To: cluster-devel.redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit 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.
