  cpuset: remove is_prs_invalid helper (2025-09-22 12:57:46 -1000)

----------------------------------------------------------------
cgroup: Changes for v6.18

- Extensive cpuset code cleanup and refactoring work with no functional
  changes: CPU mask computation logic refactoring, introducing new helpers,
  removing redundant code paths, and improving error handling for better
  maintainability.

- A few bug fixes to cpuset including fixes for partition creation failures
  when isolcpus is in use, missing error returns, and null pointer access
  prevention in free_tmpmasks().

- Core cgroup changes include replacing the global percpu_rwsem with
  per-threadgroup rwsem when writing to cgroup.procs for better scalability,
  workqueue conversions to use WQ_PERCPU and system_percpu_wq to prepare for
  workqueue default switching from percpu to unbound, and removal of unused
  code including the post_attach callback.

- New cgroup.stat.local time accounting feature that tracks frozen time
  duration.

- Misc changes including selftests updates (new freezer time tests and
  backward compatibility fixes), documentation sync, string function safety
  improvements, and 64-bit division fixes.
