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"
