From: Artem Bityutskiy Date: Wed, 6 Jun 2012 15:56:56 +0000 (+0300) Subject: affs: introduce VFS superblock object back-reference X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a215fef7edfdcd8948037ceb3060b9ae7ebcef8b;p=linux-beck.git 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.
