Subject: mm/list_lru.c: use list_lru_walk_one() in list_lru_walk_node()

Patch series "mm/list_lru: Add list_lru_shrink_walk_irq() and a user".

This series removes the local_irq_disable() around list_lru_shrink_walk()
(as used by mm/workingset) by adding list_lru_shrink_walk_irq().  Vladimir
Davydov preferred this over an `irq' argument which I added to struct
list_lru.

The initial post (of this series) received a Reviewed-by tag by Vladimir
Davydov which I added to each patch of the series.  The series applies on
top of akpm's tree which has Kirill's shrink_slab series and does not
clash with it (akpm asked me to wait a week or so and repost it then).

I tested the code paths by triggering the OOM-killer via memory over
commit and lockdep did not complain (nor did I see any warnings).


This patch (of 4):

list_lru_walk_node() invokes __list_lru_walk_one() with -1 as the
memcg_idx parameter.  The same can be achieved by list_lru_walk_one() and
passing NULL as memcg argument which then gets converted into -1.  This is
a preparation step when the spin_lock() function is lifted to the caller
of __list_lru_walk_one().  Invoke list_lru_walk_one() instead
__list_lru_walk_one() when possible.
