The getpid() function is called in a couple of places in bpftool to craft links of the shape "/proc/<pid>/...". Instead, it is possible to use the "/proc/self/" shortcut, which makes things a bit easier, in particular in jit_disasm.c. Do the replacement, and remove the includes of <sys/types.h> from the relevant files, now we do not use getpid() anymore.

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.
