The current implementation uses nested loops: first iterating over all online nodes, then over zones within each node. This can be simplified by using the for_each_populated_zone() macro which directly iterates through all populated zones. This change: 1. Removes the intermediate init_zones_in_node() function 2. Simplifies init_early_allocated_pages() to use direct zone iteration 3. Updates init_pages_in_zone() to take only zone parameter and access node_id via zone->zone_pgdat The functionality remains identical, but the code is cleaner and more maintainable.

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.
