From c36f9d3d2c3e17f9eef1d2f47a63c91d51d55e87 Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Wed, 8 Nov 2023 20:46:02 +0000 Subject: [PATCH] mm: remove test_set_page_writeback() Patch series "Make folio_start_writeback return void". Most of the folio flag-setting functions return void. folio_start_writeback is gratuitously different; the only two filesystems that do anything with the return value emit debug messages if it's already set, and we can (and should) do that internally without bothering the filesystem to do it. This patch (of 4): There are no more callers of this wrapper.
