====================
af_unix: Random improvements for GC.
If more than 16000 inflight AF_UNIX sockets exist on a host, each
sendmsg() will be forced to wait for unix_gc() even if a process
is not sending any FD.
This series tries not to impose such a penalty on sane users who
do not send AF_UNIX FDs or do not have inflight sockets more than
SCM_MAX_FD * 8.
The first patch can be backported to -stable.
Cleanup patches for commit 69db702c8387 ("io_uring/af_unix: disable
sending io_uring over sockets") and large refactoring of GC will
be followed later.

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.
