[linux]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

'rds_ib_dereg_odp_mr' has been unused since the original
commit 2eafa1746f17 ("net/rds: Handle ODP mr
registration/unregistration").

Remove it.

nit: Maybe commit lines are best not line-wrapped.
     I'm unsure.

The above not withstanding, this looks good to me.

Yeh I wasn't too sure, checkpatch seems to have code
to deal with it, so it is expecting it could be wrapped:

  # A commit match can span multiple lines so this block attempts to find a
  # complete typical commit on a maximum of 3 lines

This patch looks fine to me, the struct is indeed unused at this point.
Thanks for the clean up!

Hi,
  Does anyone know who might pick this one up - I don't think
it's in -next yet?

1. We are in merge window and this patch is not a bug fix, so it should
   wait until the next merge window.
2. Title should be net/rds ... and not RDMA/rds ...
3. netdev is closed right now, so it should be resubmitted after next merge
   window ends.

Thanks

Yeh I did wonder; it was posted and reviewed back at the start of June.

OK, I can easily fix that.

When you say 'resubmitted' - you mean reposted to the lists with the amended
title? Or what?

I've not been using Fixes on these, because they
have no actual consequence - there's no need
for stable or downstream to pick them up, which is
what Fixes is often used for.
