Subject: lock_sock or sock_hold ?

hello everyone,

can you please be kind and help me understand the differences between
lock_sock and sock_hold ?

i can see that lock_sock takes a spin lock (bh) to mark owned = 1, and
then takes a mutex, whereas sock_hold only increases the atomic
refcnt.

but how do i know which of them I should use ?

i'm puzzled as to when should those two different APIs be used..

thank you a lot
