From 5c44aa21f0863270efbf03a4d5bd6b75fec4134c Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Mon, 25 Nov 2024 18:01:14 +0000 Subject: [PATCH] isofs: Partially convert zisofs_read_folio to use a folio Remove several hidden calls to compound_head() and references to page->index. More needs to be done to use folios throughout the zisofs code.
