When task A hold the sk owned in tcp_sendmsg, if lots of packets arrive and the packets will be added to backlog queue. The packets will be handled in release_sock called from tcp_sendmsg. When the sk_backlog is removed from sk, the length will not decrease until all the packets in backlog queue are handled. This may leads to the new packets be dropped because the lenth is too big. So set the lenth to 0 immediately after it's detached from sk.
Length?
