Hello, Roger.

show_workqueue_state() is a better choice to me. However, only freezable
workqueue is able to affect suspend flow. So, is there other mailing
list discussing about showing freezable workqueue state only?? Maybe we
can use that API in this case. Thanks very much.

freezable workqueue means workqueue is created with flag WQ_FREEZABLE.
It's for debugging anyway and workqueue dumps usually are pretty
short.  I don't think it's fine to use the same function.  We can add
flags in the printouts but I'm not even sure that'd be necessary.

Thanks.
