From a215fef7edfdcd8948037ceb3060b9ae7ebcef8b Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Wed, 6 Jun 2012 18:56:56 +0300 Subject: affs: introduce VFS superblock object back-reference Add an 'sb' VFS superblock back-reference to the 'struct affs_sb_info' data structure - we will need to find the VFS superblock from a 'struct affs_sb_info' object in the next patch, so this change is jut a preparation.
