  workqueue: Rename show_cpu_pool{s,}_hog{s,}() to reflect broadened scope (2026-03-06 06:38:16 -1000)

----------------------------------------------------------------
workqueue: Fixes for v7.0-rc3

- Improve workqueue stall diagnostics: dump all busy workers (not just
  running ones), show wall-clock duration of in-flight work items, and
  add a sample module for reproducing stalls.

- Fix POOL_BH vs WQ_BH flag namespace mismatch in pr_cont_worker_id().

- Rename pool->watchdog_ts to pool->last_progress_ts and related
  functions for clarity.
