#     Merge branch 'for-5.4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
#     
#     Pull cgroup fix from Tejun Heo:
#      "There's an inadvertent preemption point in ptrace_stop() which was
#       reliably triggering for a test scenario significantly slowing it down.
#     
#       This contains Oleg's fix to remove the unwanted preemption point"
#     
#     * 'for-5.4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
#       cgroup: freezer: call cgroup_enter_frozen() with preemption disabled in ptrace_stop()
