trivia:
ipv4/sockglue.c uses the ternary '? 1 : 0' convention for this.
It might be nicer to be consistent.
Then again sockglue.c is inconsistent about that too.
net/ipv4/ip_sockglue.c:736: inet->hdrincl = val ? 1 : 0;
net/ipv4/ip_sockglue.c:743: inet->nodefrag = val ? 1 : 0;
net/ipv4/ip_sockglue.c:746: inet->bind_address_no_port = val ? 1 :
0;
net/ipv4/ip_sockglue.c:754: inet->recverr = !!val;
net/ipv4/ip_sockglue.c:772: inet->mc_loop = !!val;
net/ipv4/ip_sockglue.c:1123: inet->freebind = !!val;
There's no change to object code either way.
