Let's simplify and reduce code indentation. In the RMAP_LEVEL_PTE case, we already check for nr when computing partially_mapped. For RMAP_LEVEL_PMD, it's a bit more confusing. Likely, we don't need the "nr" check, but we could have "nr < nr_pmdmapped" also if we stumbled into the "/* Raced ahead of another remove and an add? */" case. So let's simply move the nr check in there. Note that partially_mapped is always false for small folios. No functional change intended.

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 reStructuredText 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.
