It's convenient to have page->objects initialized before calling into account_slab_page(). In particular, this information can be used to pre-alloc the obj_cgroup vector. Let's call account_slab_page() a bit later, after the initialization of page->objects. This commit doesn't bring any functional change, but is required for further optimizations.

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.
