Hi Dave & Jakub,

please apply the following patches to netdev's net-next tree.

These patches do some preparation to make ISM available for uses beyond
SMC-D, and a bunch of cleanups.

Thanks,
Wenjia

Heiko Carstens (1):
  net/smc: Eliminate struct smc_ism_position

Stefan Raspl (3):
  s390/ism: Cleanups
  net/smc: Pass on DMBE bit mask in IRQ handler
  net/smc: Enable module load on netlink usage

Hello Wenjia,

Making ISM available for others sounds great. I proposed a RFC [1] last
week. The RFC brings an ISM-like device to accelerate inter-VM scenario.
I am wondering the plan about this, which may help us. And hope to hear
from you about the RFC [1]. Thank you.

Cheers,

Hi Tony,

Thank you for the review first of all!

Besides this serie of patches, we are working on some follow-on patches. 
If you need, we can send you an RFC, so that you can adjust code 
according to it.

About the RFC you mentioned, it does look appealing even for us. But 
still some in-house discussions are going on in order to make sure there 
would be no risk for us. We will let you know as soon as we reach a 
consensus.

Best
Wenjia
