   1 From: ReiserFS Development <reiserfs-devel@vger.namesys.com>
   2 Subject: [PATCH] vfs: Add ->sync_inodes super operation for reiser4
   3
   4  This patch adds the ->sync_inodes superblock operation for use with reiser4.
   5
   6  FIle systems without this operation will still use the generic implementation.
