Just in case you want to apply this to your tree too: > Acked-by: Heiko Carstens <hca@xxxxxxxxxxxxx> Thank you for looking at this and confirming I had read that the code properly and that the do_exit reference was no longer used. I will probably take this through my tree as well just so I don't have that trailing do_exit reference. At this point I will give things a bit more for people to review or say something about the other changes and if there is no negative feedback I think I will just apply the lot. Eric
