Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace fix from Eric Biederman:
"This fixes a race between put_ucounts and get_ucounts that can cause a
use after free. The fix works by simplifying the code and so there is
not even a temptation to be clever and play spinlock vs atomic
reference games"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
ucount: Remove the atomicity from ucount->count
