The optional parameter "map MAP" can be added to "bpftool iter" command to create a bpf iterator for map elements. For example, bpftool iter pin ./prog.o /sys/fs/bpf/p1 map id 333 For map element bpf iterator "map MAP" parameter is required. Otherwise, bpf link creation will return an error. Quentin Monnet kindly provided bash-completion implementation for new "map MAP" option.

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.
