From 988439f828b24fba8784cbd4d713d87cabd807cf Mon Sep 17 00:00:00 2001 From: Jan Kara Date: Mon, 17 Dec 2012 11:08:11 +0100 Subject: [PATCH 2/2] ubifs: Wait for page writeback to provide stable pages When stable pages are required, we have to wait if the page is just going to disk and we want to modify it. Add proper callback to ubifs_vm_page_mkwrite().
