Merge branch 'tcp-rework-tcp_v-4-6-_send_check'
Eric Dumazet says:
====================
tcp: rework tcp_v{4,6}_send_check()
tcp_v{4,6}_send_check() are only called from __tcp_transmit_skb()
They currently are in different files (tcp_ipv4.c and tcp_ipv6.c)
thus out of line.
This series move them close to their caller so that compiler
can inline them.
For all patches in the series:
