Now that we don't use the hash value or shift in nested_table_alloc() there is room for simplification. We only need to pass a "is this a leaf" flag to nested_table_alloc(), and don't need to track as much information in rht_bucket_nested_insert(). Note there is another minor cleanup in nested_table_alloc() here. The number of elements in a page of "union nested_tables" is most naturally PAGE_SIZE / sizeof(ntbl[0]) The previous code had PAGE_SIZE / sizeof(ntbl[0].bucket) which happens to be the correct value only because the bucket uses all the space in the union.

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.
