Well, I don't understand how to read the output here, I'm sorry. Since this
patch modifies the user_struct, it has a dependency on the following patch
just merged into Linus tree :
712f4aa ("unix: properly account for FDs passed over unix sockets")
That's probably why you have the "cannot apply" error above.
