Lookup for the first map named "filtered_pids" and, if augmenting syscalls, i.e. if a BPF event is present and the "__augmented_syscalls__" is present, then fill in that map with the pids to filter, be it feedback loop ones (perf trace's pid, its father if it is "sshd", more auto-filtered in the future) or the ones explicitely stated in the tool command line via --filter-pids. The code to actually fill in the map comes next.

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.
