Merge branch 'for-5.2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
Pull cgroup fix from Tejun Heo: "The cgroup2 freezer pulled in this cycle broke strace. This pull request includes a workaround for the problem. It's not a complete fix in that it may cause spurious frozen state flip-flops which is fairly minor. Will push a full fix once it's ready" * 'for-5.2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: signal: unconditionally leave the frozen state in ptrace_stop()
