[PATCH 0/3] workqueue: Fix table in wq_dump.py for large number of workqueues

[Breno Leitao]

On larger machines (e.g. 316 CPUs, 2 NUMA nodes), the "Unbound
workqueue -> node_nr/max_active" section of wq_dump.py has column
alignment issues.

Values like max_active=2048 exceed the hardcoded minimum field width of 3,
causing the header and data rows to misalign.

This series cleans up the formatting:

 1. Remove the backslash separator from the header

 2. Widen format specifiers for 4-digit values and right-align
    nr/max as a single string

 3. Add "NODE" prefix to all node columns for clarity.
    * Although the original code intentionally only labeled the first column,
      the bare numbers for subsequent nodes create more confusion than they
      help. Labeling all columns makes the output self-explanatory.

Before:
  [          workqueue           \ min max  NODE 0       1     dfl ]
  events_unbound                     8 2048   0/2048   0/  8   0/2048
  netns                              1   1   0/  1   0/  1   0/  1
  async                            1024 1024   0/1024   0/1024   0/1024
  cpuset_migrate_mm                  1   1   0/  1   0/  1   0/  1

After:
  [           workqueue             min  max    NODE 0    NODE 1       dfl ]
  events_unbound                      8 2048    0/2048       0/8    0/2048
  netns                               1    1       0/1       0/1       0/1
  async                            1024 1024    0/1024    0/1024    0/1024
  cpuset_migrate_mm                   1    1       0/1       0/1       0/1
