Look at how this datastructure actually works before making
such suggestions, don't just look at the context provided
purely by a patch.
"inet_timewait_sock" begins with a "struct sock_common"
which is where the atomic_t is, and:
#define tw_refcnt __tw_common.skc_refcnt
So you would have to change struct sock_common over to kref, and thus
the entire networking, in order to make such a change.
I see zero value in this. There are millions of more useful things to
invest that kind of time on.
But you would have seen this instantly if you had spent 5 seconds
looking at how these datastructures are defined. Instead you choose
to make me do it and explain it to you instead.
