====================
Commit ae24345da5 ("bpf: Implement an interface to register
bpf_iter targets") and its subsequent commits in the same patch set
introduced bpf iterator, a way to run bpf program when iterating
kernel data structures.
This patch set addressed some followup issues. One big change
is to allow target to pass ctx arg register types to verifier
for verification purpose. Please see individual patch for details.
Changelogs:
v1 -> v2:
. add "const" qualifier to struct bpf_iter_reg for
bpf_iter_[un]reg_target, and this results in
additional "const" qualifiers in some other places
. drop the patch which will issue WARN_ONCE if
seq_ops->show() returns a positive value.
If this does happen, code review should spot
this or author does know what he is doing.
In the future, we do want to implement a
mechanism to find out all registered targets
so we will be aware of new additions.

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.
