Hi Roland,
This series from Sagi, Ariel and Roi consists of:
- Last batch of iser control plane stability fixes (patches 1-10)
Mainly in the area of combinations of multi-connections concurrent
establishment and/or teardown and/or device removal and/or iscsid killed.
- Various performance enhancements (patches 11-16) done through the
engine warming towards the MQ work
Remove atomic manipulation in the hot path
Optimize cq polling
Use single CQ for TX and RX and suppress most of the send completions.
- Sone nit fixes and kernel-doc fixes (patches 17-21)
It should be applied on "Signature feature update" Sagi posted (now formally
an upstream maintainer..) a short while ago for 3.18 (and you agreed to take).
In 3.18 we happily mark iSER's 20'th upstream anniversary (2.6.18..3.18),
and we're really excited for the challenge of going over 2M IOPS (current
IO rate for single initiator) to whatever many million IOPS we can do with MQ.
Or and the team.
