    [PATCH] VFS: Permit filesystem to perform statfs with a known root dentry · 726c3342
    David Howells authored Jun 23, 2006
    
    
    Give the statfs superblock operation a dentry pointer rather than a superblock
    pointer.
    
    This complements the get_sb() patch.  That reduced the significance of
    sb->s_root, allowing NFS to place a fake root there.  However, NFS does
    require a dentry to use as a target for the statfs operation.  This permits
    the root in the vfsmount to be used instead.
    
    linux/mount.h has been added where necessary to make allyesconfig build
    successfully.
    
    Interest has also been expressed for use with the FUSE and XFS filesystems.
