Oh, oops, I forgot about that. I mentioned the fix for that in my
original email and it seems I wasn't testing apples to apples for my
testing today. During my testing today, the branch with the reverted
commits had the fix for that commit while the branch with Bharat's patch
didn't.
I just did a test with both Bharat's patch and 5a7a88f1b4, and
everything is working correctly again.
So that's great, we just need these patches to be picked up by the
stable kernels.
Thanks,
Logan
