To avoid putting ifdefs within a function, how about adding:

#if defined(CONFIG_EXPORTFS) || defined(CONFIG_EXPORTFS_MODULE)
#define set_export_ops(sb, ops)		sb->s_export_op = ops
#else
#define set_export_ops(sb, ops)		0
#endif

That way you can get rid of the function pointer from the struct
superblock too.

But Dave Woodhouse is going to kill you for adding another
CONFIG_*_MODULE dependency.
