[PATCH v2 0/3] Fix errors in FIN timeout logic

[David Gibson <david@gibson.dropbear.id.au>]

While investigating bug 179, I found a number of things that confused
me about the TCP timer handling.  One of them, I think I figured out
what's going on and what should be done about it.  So, here are the
changes.  This is mostly about FIN handling and only tangentially
about the timer, but it does at least slightly simplify the timer
handling while I figure out the rest of it.

Changes in v2:
 * Stefano pointed out some errors in my guesses at the history of
   things, evised commit message of 2/3 accordingly
 * Added 3/3 checking for shutdown(2) failures

David Gibson (3):
  tcp: Retransmit FINs like data segments
  tcp: Eliminate FIN_TIMEOUT
  tcp, tcp_splice: Check for failures of shutdown(2)
