From f02e26f8d90f8cde98314c72c2e890bc281a8346 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 23 Nov 2010 14:38:02 +0100 Subject: hfsplus: avoid useless work in hfsplus_sync_fs There is no reason to write out the metadata inodes or volume headers during a non-blocking sync, as we are almost guaranteed to dirty them again during the inode writeouts.
