With zcache using zbud, strange locking scenarios are
observed. The first problem seen is:
Core 2 waiting on mapping->tree_lock which is taken by core 6
do_raw_spin_lock
raw_spin_lock_irq
atomic_cmpxchg
page_freeze_refs
__remove_mapping
shrink_page_list
Core 6 after taking mapping->tree_lock is waiting on zbud pool lock
which is held by core 5
zbud_alloc
zcache_store_page
__cleancache_put_page
cleancache_put_page
__delete_from_page_cache
spin_unlock_irq
__remove_mapping
shrink_page_list
shrink_inactive_list
Core 5 after taking zbud pool lock from zbud_free received an IRQ, and
after IRQ exit, softirqs were scheduled and end_page_writeback tried to
lock on mapping->tree_lock which is already held by Core 6. Deadlock.

This shows that allowing softirqs while holding zbud pool lock
can result in deadlocks. To fix this, 'commit 6a1fdaa36272
("mm: zbud: prevent softirq during zbud alloc, free and reclaim")'
decided to take spin_lock_bh during zbud_free, zbud_alloc and
zbud_reclaim. But this resulted in another deadlock.

__cleancache_put_page()
__delete_from_page_cache()
__remove_mapping()
shrink_page_list()
Here, the spin_unlock_bh resulted in explicit invocation of do_sofirq,
which resulted in the acquisition of mapping->tree_lock which was already
taken by __remove_mapping.
The new fix considers the following facts.
1) zcache_store_page is always be called from __delete_from_page_cache
with mapping->tree_lock held and interrupts disabled. Thus zbud_alloc
which is called only from zcache_store_page is always called with
interrupts disabled.
2) zbud_free and zbud_reclaim_page can be called from zcache with or
without interrupts disabled. So an interrupt while holding zbud pool
lock can result in do_softirq and acquisition of mapping->tree_lock.
(1) implies zbud_alloc need not explicitly disable bh. But disable
interrupts to make sure zbud_alloc is safe with zcache, irrespective
of future changes. This will fix the second scenario.
(2) implies zbud_free and zbud_reclaim_page should use spin_lock_irqsave,
so that interrupts will not be triggered and inturn softirqs.
spin_lock_bh can't be used because a spin_unlock_bh can triger a softirq
even in interrupt context. This will fix the first scenario.

if the cpuset originally requested that that cpu was part of the cpuset, that
