This is in preparation for the removal of find_get_pages_range_tag(). Now also supports the use of large folios. Since tofind might be larger than the max number of folios in a folio_batch (15), we loop through filling in wdata->pages pulling more batches until we either reach tofind pages or run out of folios. This function may not return all pages in the last found folio before tofind pages are reached.

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.
