In unplug_oldest_pwq(), the first inactive work item on the
pool_workqueue is activated correctly. However, if multiple inactive
works exist on the same pool_workqueue, subsequent works fail to
activate because wq_node_nr_active.pending_pwqs is empty — the list
insertion is skipped when the pool_workqueue is plugged.
Fix this by checking for additional inactive works in
unplug_oldest_pwq() and updating wq_node_nr_active.pending_pwqs
accordingly.
v2:
- Use pwq_activate_first_inactive(pwq, false) rather than open coding
list operations (Tejun)

This bug was first reported by Google, where the Xe driver appeared to
hang due to a fencing signal not completing. We traced the issue to work
items not being scheduled, and it can be trivially reproduced on drm-tip
with the following commands:
shell0:
for i in {1..100}; do echo "Run $i"; xe_exec_threads --r \
threads-rebind-bindexecqueue; done
shell1:
for i in {1..1000}; do echo "toggle $i"; echo f > \
/sys/devices/virtual/workqueue/cpumask; echo ff > \
/sys/devices/virtual/workqueue/cpumask; echo fff > \
/sys/devices/virtual/workqueue/cpumask ; echo ffff > \
/sys/devices/virtual/workqueue/cpumask; sleep .1; done

Thanks for fixing this bug. However, calling pwq_activate_first_inactive
twice can be a bit hard to understand. Will modifying
pwq_tryinc_nr_active() like the following works?

No problem — I think this one has been lurking around for a while, and
we’ve just papered over it in Xe for a couple of years.
> twice can be a bit hard to understand. Will modifying pwq_tryinc_nr_active()
I actually think it makes quite a bit of sense, as it matches what
__queue_work does if two items are added back-to-back on an ordered
workqueue — the first one updates the nr_active counts and activates,
and the second one updates the pending_pwqs.

My initial thought was that your snippet should work — in fact, it does
for a while (drm-tip hangs almost immediately), but eventually I do get
a hang when running my reproducer, whereas with this patch I don’t. I
can’t reason exactly why — maybe it’s because
node_activate_pending_pwq() can find a plugged pwq, but that’s just a
guess.
