[ Upstream commit 24c6a097b5a270e05c6e99a99da66b91be81fd7d ] The get_partial() interface used in ___slab_alloc() may return a single object in the "kmem_cache_debug(s)" case, in which we will just return the "freelist" object. Move this handling up to prepare for later changes. And the "pfmemalloc_match()" part is not needed for node partial slab, since we already check this in the get_partial_node().

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.
