Hi,

Thank you for reviewing.
I have a question.

As far as reading Documentation/printk-formats.txt and 
pointer() in lib/vsprintf.c, %pMR is not defined.
I guess you mean %pM, don't you?

I've tried following code, and it works as expected.

		baswap(&src_baswapped, &bt->src);
		baswap(&dst_baswapped, &bt->dst);

		seq_printf(seq, "%pK %-6d %-6u %-6u %-6u %-6lu %pM %pM %-6lu",
			   sk,
			   atomic_read(&sk->sk_refcnt),
			   sk_rmem_alloc_get(sk),
			   sk_wmem_alloc_get(sk),
			   sock_i_uid(sk),
			   sock_i_ino(sk),
			   &src_baswapped,
			   &dst_baswapped,
			   bt->parent? sock_i_ino(bt->parent): 0LU);
