Nothing crazy in here I suppose, I somewhat wonder why you went through
the trouble, but meh.
If you are asking why I have proposed this patchset, then the answer is
simple, 1st I've tried to find a way to move internal i915 helper to core
(see patch 7).
Then I was looking for possible other users of this helper. And apparently
there are many of them, patches 3-7 shows some.
You want me to take this through te locking tree (for the next cycle,
not this one) where I normally take atomic things or does someone else
want this?
If you could take it I will be happy.
OK, I'll go queue it in tip/locking/core after -rc1. Thanks!
Is this where the series fell between the cracks, or was there some
follow-up that I missed?
I think this would still be useful. Andrzej, would you mind rebasing and
resending if there are no objections?
The patchset was rejected/dropped by Linus at the pull-request stage.
He didn't like many things, but the most __xchg name. However he was
quite positive about i915 name fetch_and_zero.
I can try to revive patchset with fetch_and_zero, and maybe
fetch_and_set, instead of __xchg.
