Subject: [PATCH v1 net-next 0/6] tcp: Clean up SYN+ACK RTO code and apply max RTO.

Patch 1 - 4 are misc cleanup.

Patch 5 applies max RTO to non-TFO SYN+ACK.

Patch 6 adds a test for max RTO of SYN+ACK.


Kuniyuki Iwashima (6):
  tcp: Call tcp_syn_ack_timeout() directly.
  tcp: Remove timeout arg from reqsk_queue_hash_req().
  tcp: Remove redundant init for req->num_timeout.
  tcp: Remove timeout arg from reqsk_timeout().
  tcp: Apply max RTO to non-TFO SYN+ACK.
  selftest: packetdrill: Add max RTO test for SYN+ACK.
