[GIT PULL] Landlock fix for v7.3-rc5

Hi,

This mainly fixes the Landlock tracepoint support merged this cycle so
that denial and rule events report the intended policy context, whether
through tracefs or BTF-visible callbacks.  The size comes from
propagating the corrected contract through event definitions and
producers, adding new tests for the reported context, and updating the
documentation.  This PR also improves annotation and fixes a GCC 16
build warning.

Please pull these changes for v7.3-rc5 .  These commits have been part
of latest linux-next releases and merge cleanly with your master branch.

Test coverage for security/landlock is 91.6% of 2625 lines according to
LLVM 22, and it was 91.6% of 2574 lines before this PR.

Regards,
 Mickaël
