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.

As suggested by Andrew Morton in [1] add selftests for the new sys_pidfd_send_signal() syscall: /* test_pidfd_send_signal_syscall_support */ Test whether the pidfd_send_signal() syscall is supported and the tests can be run or need to be skipped. /* test_pidfd_send_signal_simple_success */ Test whether sending a signal via a pidfd works. /* test_pidfd_send_signal_exited_fail */ Verify that sending a signal to an already exited process fails with ESRCH. /* test_pidfd_send_signal_recycled_pid_fail */ Verify that a recycled pid cannot be signaled via a pidfd referring to an already exited process that had the same pid (cf. [2], [3]).
