Hello, This is another version considering the suggestions. Thanks! I didn't convert to list_head yet because a lot more code needs to be changed so I'd rather leave that to another patch. 8<--------- Almost all igmp functions accessing inet->mc_list are protected by rtnl_lock(), but there is one exception which is ip_mc_sf_allow(), so there is a chance of either ip_mc_drop_socket or ip_mc_leave_group remove an entry while ip_mc_sf_allow is running causing a crash.

Applied to net-next-2.6, thanks.
