Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull ptrace fixes from Eric Biederman:
"This is just two very minor fixes:
- prevent ptrace from reading unitialized kernel memory found twice
- restore a missing smp_rmb in ptrace_may_access and add comment tp
it so it is not removed by accident again.
Apologies for being a little slow about getting this to you, I am
still figuring out how to develop with a little baby in the house"
