From c18cb57f81d42eb408fa7f0fb15b9f4f3f9998fb Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Mon, 15 Mar 2010 20:26:02 -0400 Subject: [PATCH] vfs: Remove the range_cont writeback mode. commit 74baaaaec8b4f22e1ae279f5ecca4ff705b28912 upstream. Ext4 was the only user of range_cont writeback mode and ext4 switched to a different method. So remove the range_cont mode which is not used in the kernel.
