Revert "tcp: bind() fix when many ports are bound"
This reverts two commits: fda48a0d7a8412cedacda46a9c0bf8ef9cd13559 tcp: bind() fix when many ports are bound and a follow-on fix for it: 6443bb1fc2050ca2b6585a3fa77f7833b55329ed ipv6: Fix inet6_csk_bind_conflict() It causes problems with binding listening sockets when time-wait sockets from a previous instance still are alive. It's too late to keep fiddling with this so late in the -rc series, and we'll deal with it in net-next-2.6 instead. Signed-off-by: David S. Miller <davem@davemloft.net>
