Historically when freeing pages, free_one_page() assumed that callers
had IRQs disabled and the zone->lock could be acquired with spin_lock().
This confuses the scope of what local_lock_irq is protecting and what
zone->lock is protecting in free_unref_page_list in particular.

That commit has revealed another bug in cifs_mount() where we failed to

__free_pages_ok() disables IRQs before calling a common helper
free_one_page() that acquires the zone lock. This is not safe according
to Documentation/locking/locktypes.rst and in this context, IRQ disabling
is not protecting a per_cpu_pages structure either or a local_lock would
be used.

There is a lack of clarity of what exactly local_irq_save/local_irq_restore
