    Subject[PATCH 5/6] hfs: introduce VFS superblock object back-reference
    Date
    From: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

    Add an 'sb' VFS superblock back-reference to the 'struct hfs_sb_info' data
    structure - we will need to find the VFS superblock from a
    'struct hfs_sb_info' object in the next patch, so this change is jut a
    preparation.

    Remove few useless newlines while on it.
