Pull cgroup fixes from Tejun Heo: - Fix seqcount lockdep assertion failure in cgroup freezer on PREEMPT_RT. Plain seqcount_t expects preemption disabled, but PREEMPT_RT spinlocks don't disable preemption. Switch to seqcount_spinlock_t to properly associate css_set_lock with the freeze timing seqcount. - Misc changes including kernel-doc warning fix for misc_res_type enum and improved selftest diagnostics. * tag 'cgroup-for-6.18-rc2-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup: cgroup/misc: fix misc_res_type kernel-doc warning selftests: cgroup: Use values_close_report in test_cpu selftests: cgroup: add values_close_report helper cgroup: Fix seqcount lockdep assertion in cgroup freezer
