Honestly speaking I wasn't sure if anyone apart from Qcom will ever use this
feature when I wrote it first and I am quite surprised and happy to see your
patches.

They are mostly very neat and clean patches and I don't have complaints with
most of them. Lets see what comments others provide on them.

Thanks.
