From 10096fb1088e5c89b10772a1dfbe9682ecae5cea Mon Sep 17 00:00:00 2001 From: Anton Altaparmakov Date: Thu, 21 Aug 2014 11:09:27 +0100 Subject: Export sync_filesystem() for modular ->remount_fs() use This patch changes sync_filesystem() to be EXPORT_SYMBOL(). The reason this is needed is that starting with 3.15 kernel, due to Theodore Ts'o's commit 02b9984d6408 ("fs: push sync_filesystem() down to the file system's remount_fs()"), all file systems that have dirty data to be written out need to call sync_filesystem() from their ->remount_fs() method when remounting read-only. As this is now a generically required function rather than an internal only function it should be EXPORT_SYMBOL() so that all file systems can call it.
