Merge branch 'exec-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull execve fix from Eric Biederman: "While working on my exec cleanups I found a bug in exec that I introduced by accident a couple of years ago. I apparently missed the fact that bprm->file can change. Now I have a very personal motive to clean up exec and make it more approachable. The change is just moving woud_dump to where it acts on the final bprm->file not the initial bprm->file. I have been careful and tested and verify this fix works" * 'exec-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: exec: Move would_dump into flush_old_exec
