Wake Liu 05d89fe7e4 selftests/timers: Clean up kernel version check in posix_timers 
Several tests in the posix_timers selftest which test timer behavior
related to SIG_IGN fail on kernels older than 6.13. This is due to
a refactoring of signal handling in commit caf77435dd ("signal:
Handle ignored signals in do_sigaction(action != SIG_IGN)").

A previous attempt to fix this by adding a kernel version check to each
of the nine affected tests was suboptimal, as it resulted in emitting
the same skip message nine times.

Following the suggestion from Thomas Gleixner, this is refactored to
perform a single version check in main(). To satisfy the kselftest
framework's requirement for the test count to match the declared plan,
the plan is now conditionally set to 10 (for older kernels) or 19.

While setting the plan conditionally may seem complex, it is the
better approach to avoid the alternatives: either running tests on
unsupported kernels that are known to fail, or emitting a noisy series
of nine identical skip messages. A single informational message is now
printed instead when the tests are skipped.

README 

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.
