Tushar Vyavahare says: ==================== selftests/xsk: Add tests for XDP tail adjustment in AF_XDP This patch series adds tests to validate the XDP tail adjustment functionality, focusing on its use within the AF_XDP context. The tests verify dynamic packet size manipulation using the bpf_xdp_adjust_tail() helper function, covering both single and multi-buffer scenarios. v1 -> v2: 1. Retain and extend stream replacement: Keep `pkt_stream_replace` unchanged. Add `pkt_stream_replace_ifobject` for targeted ifobject handling. 2. Consolidate patches: Merge patches 2 to 6 for tail adjustment tests and check. v2 -> v3: 1. Introduce `adjust_value` to replace `count` for clearer communication with userspace. v3 -> v4: 1. Remove `testapp_adjust_tail_common()`. [Maciej] 2. Add comments and modify code for buffer resizing logic in test cases (shrink/grow by specific byte sizes for testing purposes).

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.
