Hello Mark,

It is hard for me to extract the relevant patches from those emails.


I would love to finish this project but I am not sure how. It seems we need
to:


1) Evaluate the patches that Baolin suggests as a simpler alternative.

2) Test them in an Android kernel with AAudio MMAP.


If you can provide a clear description of the latest set of patches then
maybe I can work with someone in-house to test this.


I am open to suggestions.
