Yeah, pls split this into one patch per area, with a suitable patch
subject prefix. Look at git log of each file to get a feeling for what's
the standard in each area.

Then scripts/get_maintainers.pl will also give you a more focues list of
relevant people for each part.

fwiw, one of those four is dup of a patch that I've already pushed to
msm-next for drm/msm (which seems to be an argument for splitting up a
treewide patch.. which seems something quite scriptable, but up to you
whether you want to bother with that.. either way drm/msm is ;;-clean
now)

FWIW, the amdgpu and scheduler changes have already been fixed for -next.

I just stage patches like this behind linux-next.  So if your stuff in
in -next, you'll never notice a thing.

This part is actually pretty annoying.

I hacked up a script (below) which seems to do a reasonable job in most
cases.

For this patch it gives:

  $ for f in $(git ls-files -m); do ./guess-prefix.py $f; done
  ARC: 
  ARC: 
  ARM: 
  arm64: ptrace: 
  KVM: PPC: 
  powerpc/powernv:
  x86/efi:
  block/sed-opal:
  clocksource: mips-gic: 
  clocksource/drivers/sun5i:
  drm/amd/display:
  drm/amd/powerplay:
  drm/msm/mdp5:
  drm: 
  iommu/vt-d:
  md: 
  soc: imx: gpc: 

I think those are correct except for:
 - "drm:" for "drivers/gpu/drm/scheduler" which has only a single commit.
 - "md:" for "drivers/md/raid1.c" which is tricked by inconsistent
    usage of "md: raid1:" and "md/raid1:".

But that seems like a reasonable hit rate.

Another approach would be to have a file that defines for each subsystem
what the preferred style is, but that is likely to be a PITA to
maintain.

Here was another suggestion from awhile ago

Considering the controversy how the changes should be merged, I'm going
to send a separate patch just for IMX GPC driver with a reported-by-you
tag.  Thanks for catching this.

That works for me.

Alternatively... Andrew Morton merged the patch to his -mm tree
(thanks!), so you don't need to take any action, and it will be
eventually fixed.

If you merge your own version of the patch, that's ok, too, since
Andrew will just drop his version.

Best regards,

Okay, I'm dropping my patch from IMX tree.
