Pull ucount cleanups from Eric Biederman: "While working on the ucount fixes a for v5.15 a number of cleanups suggested themselves. Little things like not testing for NULL when a pointer can not be NULL and wrapping atomic_add_negative with a more descriptive name, so that people reading the code can more quickly understand what is going on" * 'ucount-fixes-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: ucounts: Use atomic_long_sub_return for clarity ucounts: Add get_ucounts_or_wrap for clarity ucounts: Remove unnecessary test for NULL ucount in get_ucounts ucounts: In set_cred_ucounts assume new->ucounts is non-NULL
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.
