Yep, you probably right. I found lack of interest from the list of reviewers I added on phabricator, so decided to go, but may be list was not 100% pervasive. Anyway it is just 673 lines of code and I continue working on it. I plan to add scatter-gathering type of transfer and SoftDMA(®) driver, so any review of this or upcoming changes would be appreciated.
