[lvc-project] [PATCH 6.1 00/15] genetlink: Test Netlink subsystem of Linux v6.1

[Яна Башлыкова]

The motivation for this work is to improve the test coverage and
reliability of the Netlink subsystem, specifically for the core
af_netlink.c and genetlink.c components. While the subsystem is
critical for kernel-userspace communication, its coverage by the
existing selftests is quite limited.

To quantify the improvement, these new selftests achieve the following
line coverage (as measured by gcov):
- net/netlink/af_netlink.c: 84.0%
- net/netlink/genetlink.c: 88.8%

Integrating these tests into the upstream suite will provide long-term
stability and make it safer to refactor or add new features to the
Netlink core in the future.
