====================
This patch series adds various observability APIs to bpf_link:
- each bpf_link now gets ID, similar to bpf_map and bpf_prog, by which
user-space can iterate over all existing bpf_links and create limited FD
from ID;
- allows to get extra object information with bpf_link general and
type-specific information;
- implements `bpf link show` command which lists all active bpf_links in the
system;
- implements `bpf link pin` allowing to pin bpf_link by ID or from other
pinned path.
v2->v3:
- improve spin locking around bpf_link ID (Alexei);
- simplify bpf_link_info handling and fix compilation error on sh arch;
v1->v2:
- simplified `bpftool link show` implementation (Quentin);
- fixed formatting of bpftool-link.rst (Quentin);
- fixed attach type printing logic (Quentin);
rfc->v1:
- dropped read-only bpf_links (Alexei);
- fixed bug in bpf_link_cleanup() not removing ID;
- fixed bpftool link pinning search logic;
- added bash-completion and man page.

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.
