[rds-devel] [PATCH net-next v1 0/3] net/rds: RDS-TCP bug fix collection, subset 2: lock contention, state machine bugs, message drops

[Allison Henderson]

From: Allison Henderson <allison.henderson at oracle.com>

Hi all,

This is subset 2 of the RDS-TCP bug fix collection series I posted last
Oct.  The greater series aims to correct multiple rds-tcp bugs that
can cause dropped or out of sequence messages.  I've broken it down into
smaller sets to make reviews more manageable.

In this set, we correct a few RDS/TCP connection handling issues, lock
contention issues, and message some loss bugs.

The entire set can be viewed in the rfc here:

Questions, comments, flames appreciated!
Thanks!
Allison
