Merge branch 'for-4.11-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fixes from Tejun Heo: "Three cgroup fixes. Nothing critical: - the pids controller could trigger suspicious RCU warning spuriously. Fixed. - in the debug controller, %p -> %pK to protect kernel pointer from getting exposed. - documentation formatting fix" * 'for-4.11-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroups: censor kernel pointer in debug files cgroup/pids: remove spurious suspicious RCU usage warning cgroup: Fix indenting in PID controller documentation
