Sebastian Andrzej Siewior 87a5ffc163 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 `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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
