The test results from vdso_abi_test are all formatted using a series of macros: #define VDSO_TEST_PASS_MSG() "\n%s(): PASS\n", __func__ #define VDSO_TEST_FAIL_MSG(x) "\n%s(): %s FAIL\n", __func__, x #define VDSO_TEST_SKIP_MSG(x) "\n%s(): SKIP: Could not find %s\n", __func__, x which don't play nicely with automated KTAP parsers since the actual KTAP lines are in the form ok 1 with no test name and we get an additional log line such as vdso_test_gettimeofday(): PASS with no preceeding # as KTAP requires. The lack of a test name means that many automation systems will have a hard time distinguishing between the different tests or correlating results between runs, the lack of # is less severe but could potentially cause confusion. Fix these issues by rewriting all the result reporting to include both the vDSO function name being tested and (where there is one) the name of the clock being tested in the main KTAP line. Since we have tests both with and without a specific clock we abandon the helper macros and just put the format strings used directly in the ksft_ API calls. When we fail to look up the relevant vDSO symbol we add a separate print statement explaining why the skip is being done. This gives output such as: ok 1 __vdso_gettimeofday # clock_id: CLOCK_REALTIME # The time is 1700673118.58091596 ok 2 __vdso_clock_gettime CLOCK_REALTIME which is much easier for test automation to work with.

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 Restructured Text 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.
