Separate userdata and sysdata into distinct buffers to enable independent management. Previously, both were stored in a single extradata_complete buffer with a fixed size that accommodated both types of data. This separation allows: - userdata to grow dynamically (in subsequent patch) - sysdata to remain in a small static buffer - removal of complex entry counting logic that tracked both types together The split also simplifies the code by eliminating the need to check total entry count across both userdata and sysdata when enabling features, which allows to drop holding su_mutex on sysdata_*_enabled_store(). No functional change in this patch, just structural preparation for dynamic userdata allocation.

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.
