[PATCH 0/3] Add const to various core functions

[PATCH 0/3] Add const to various core functions

[ira.weiny-ral2JQCrhuEAvxtiuMwx3w]

From: Ira Weiny <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

In order to support some of Jason's comments to add const to the functions I am
adding for OPA the following patches clean up the call trees of the currently
defined functions.

They stand on their own as clean up patches.  Therefore, I am submitting them
separately from the OPA patches.

Ira Weiny (3):
  IB/core: Add const to RDMA helpers
  IB/core: Add const to device process_mad
  IB/core: Add const to agent_send_response

[PATCH 1/3] IB/core: Add const to RDMA helpers

[ira.weiny-ral2JQCrhuEAvxtiuMwx3w]

From: Ira Weiny <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The ib_device passed to the new RDMA helpers is constant.

[PATCH 2/3] IB/core: Add const to device process_mad

[ira.weiny-ral2JQCrhuEAvxtiuMwx3w]

From: Ira Weiny <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

The process_mad device function declares some parameters as "in".  Make those
parameters const and adjust the call tree under process_mad in the various
drivers accordingly.

[PATCH 3/3] IB/core: Add const to agent_send_response

[ira.weiny-ral2JQCrhuEAvxtiuMwx3w]

From: Ira Weiny <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

In order to support constant callers of agent_send_response we add const
specifiers to the its pointer arguments.

Adjust the call tree accordingly.

Doug, Jason,

Were there any issues with these clean ups?

I think they stand on their own but I can add them to the OPA series if you
prefer.

I haven't gotten to them yet.  Your 14 patch OPA addition and this were
on my queue for getting to relatively soonish.  I *thought* this touched
stuff that your 14 patch set also touched and so thought it needed to be
on top of it, so that's part of the reason why I hadn't even looked at
it yet (these emails are part of the "still new and unread" emails in my
Inbox that seem to never get to 0 ;-).

Double check that they stand on their own.  If they do, I'll review them
separately.

I understand.

They do stand on their own and they are improvements even without the OPA code.

They became precursors to the next OPA series because I am changing some core
functions.  In order to declare parameters of those core functions const the
entire call chain required updating.  Rather than mix that call chain clean up
with the new OPA code I felt it would be easier to review these as separate
clean up patches.

If this is an unorthodox procedure, is there a better way to handle something
like this?

As more and more clean up becomes necessary in the core I don't want the OPA
changes to become a huge patch series which is unwieldy to review and mostly
cleanup.  (If you count Michaels changes the "clean up" to the core which OPA
now relies on count for more patches then the actual OPA changes.) I'm trying
to reduce the review workload by making clear which patches are clean up vs
actual OPA code.

Apologies,
Ira

After responding to this email I found a 0-day build email which shows a
build warnings on this patch building ehca on PPC:

IB/core: Add const to device process_mad

I'm not sure why but sometimes my 0-day build results are delayed for quite
some time?  I'm guessing the servers prioritize kernel.org over github
accounts???  Or I'm just doing something wrong...  :-/

Sorry,
Ira

No, you did it fine.  However, if this is to be a precursor to your next
OPA patchset, then it is helpful to mention that in the cover letter
(helps me make sure I do things in the right order).

Yep, makes perfect sense.

I've seen that too.  I can't tell you what the issue is.

However, I should take this to mean there is a both a v2 of this series,
and a new OPA series on the way?

Thanks.  That allows me to clear out their existing entries in
patchworks and wait for the new ones.

[PATCH 0/3] Add const to various core functions

[ira.weiny-ral2JQCrhuEAvxtiuMwx3w]

From: Ira Weiny <ira.weiny-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>

In order to support some of Jason's comments to add const to the functions I am
adding for OPA the following patches clean up the call trees of the currently
defined functions.

They stand on their own as clean up patches.  Therefore, I am submitting them
separately from the OPA patches.

---
Changes from V1:
	Clean up 0-day build
	Clean up commit messages

Ira Weiny (3):
  IB/core cleanup: Add const to RDMA helpers
  IB/core cleanup: Add const on args - device->process_mad
  IB/core cleanup: Add const to args - agent_send_response

This is longer than I imagined, but looks good.
