wuchi 51b2ea9e4e lib/debugobjects: fix stat count and optimize debug_objects_mem_init
[ Upstream commit eabb7f1ace ]

1. Var debug_objects_allocated tracks valid kmem_cache_alloc calls, so
   track it in debug_objects_replace_static_objects.  Do similar things in
   object_cpu_offline.

2. In debug_objects_mem_init, there is no need to call function
   cpuhp_setup_state_nocalls when debug_objects_enabled = 0 (out of
   memory).

Fixes: 634d61f45d ("debugobjects: Percpu pool lookahead freeing/allocation")
Fixes: c4b73aabd0 ("debugobjects: Track number of kmem_cache_alloc/kmem_cache_free done")

README

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.

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.
