[rds-devel] [PATCH net-next v3 0/4] net/rds: RDS-TCP reconnect and fanout improvements

[Allison Henderson]

Hi all,

This is subset 4 of the larger RDS-TCP patch series I posted last
Oct.  The greater series aims to correct multiple rds-tcp issues 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 address some reconnect issues occurring during connection
teardowns, and also move connection fanout operations to a background
worker.

The entire set can be viewed in the rfc here:

Questions, comments, flames appreciated!

Thanks,
Allison
