[Intel-gfx] linux-next: manual merge of the usb tree with the drm-intel-fixes tree

[Stephen Rothwell]

[-- Attachment #1: Type: text/plain, Size: 827 bytes --]

Hi all,

Today's linux-next merge of the usb tree got a conflict in:

  drivers/gpu/drm/i915/gt/intel_engine_cs.c

between commit:

  5bc4b43d5c6c ("drm/i915: Fix up locking around dumping requests lists")

from the drm-intel-fixes tree and commit:

  4d70c74659d9 ("i915: Move list_count() to list.h as list_count_nodes() for broader use")

from the usb tree.

I fixed it up (the former removed the code changed by the latter) and
can carry the fix as necessary. This is now fixed as far as linux-next
is concerned, but any non trivial conflicts should be mentioned to your
upstream maintainer when your tree is submitted for merging.  You may
also want to consider cooperating with the maintainer of the conflicting
tree to minimise any particularly complex conflicts.

Thanks for the merge resolution.

Hmm... Currently I see that 20230127002842.3169194-4-John.C.Harrison@Intel.com
moves the code to the drivers/gpu/drm/i915/gt/intel_execlists_submission.c.

Is there any new series beside the above mentioned that touches that file and
actually _removes_ that code?

As long as the removal is limited to list_count/list_count_nodes, that's 
fine. I only moved it from one file to another because the one and only 
function that was using it was being moved to the other file. If someone 
else has found a use for the same and wants to move it to a more common 
place then great. I assume there was no conflict happening in the i915 
specific code.

I have added this fix up patch to linux-next today (more or less - this
is a hand hacked version, but you get the idea):

something awkward here.
The resolution on linux-next should align with the resolution on drm-tip
where we have the list_count still there as we preferred the version
on drm-intel-gt-next as the resolution of the conflict instead of the
fixes one.

Not following why you want to keep list_count as a local function in the 
i915 driver? Surely the correct fix is to move it to the common header 
and share the code? In which case, the correct name is 
list_count_nodes() as that is what got merged to the common header.

right. please ignore my previous email and accept my apologies for the
unnecessary noise. I had just read the commit '4d70c74659d9 ("i915: Move
 list_count() to list.h as list_count_nodes() for broader use")'
and it now the final resolution makes total sense. And that patch had
been reviewed and acked by us, so everything is good.

I just confused with other conflict that we have with our on gt-next
and -fixes tree but with an easier resolution.

Sorry,
Rodrigo.
