Hi Doug and Jason, Here is a series from Mike that fixes some issues with user SDMA. These are bit more complicated than we'd like for RC so we can go ahead and send these to next. The real goal of this series is to address some race conditions in user SDMA, the other two patches are less serious issues but still need to be addressed. --- Michael J.
