Yes. From ntfs-driver-tng/linux/fs/ntfs/fs.h:

/**
  * NTFS_SB - return the ntfs volume given a vfs super block
  * @sb:         VFS super block
  *
  * NTFS_SB() returns the ntfs volume associated with the VFS super block @sb.
  */
static inline ntfs_volume *NTFS_SB(struct super_block *sb)
{
         return sb->u.generic_sbp;
}

/**
  * NTFS_I - return the ntfs inode given a vfs inode
  * @inode:      VFS inode
  *
  * NTFS_I() returns the ntfs inode associated with the VFS @inode.
  */
static inline ntfs_inode *NTFS_I(struct inode *inode)
{
         return inode->u.generic_ip;
}
