[$] What happens to kernel staging-tree code

The staging tree was added to the kernel in 2008for the 2.6.28 development cycle as a way to ease the process ofgetting substandard device drivers into shape and merged into themainline. It has been followed by controversy for just about as long. Therecent disagreements over the EROFS and exFAT filesystems have reignited many of thearguments over whether the staging tree is beneficial to the kernelcommunity or not. LWN cannot answer that question, but we can look into what has transpired in thestaging tree in its first eleven years to see if there are any conclusionsto be drawn there.A lot of code has gone into the staging tree over the years; what happenedto it thereafter?
