  cgroup/misc: fix misc_res_type kernel-doc warning (2025-10-17 05:31:56 -1000)

----------------------------------------------------------------
cgroup: Fixes for v6.18-rc2

- 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.
