This patch test the following failures in syscall update_elem 1. The first update_elem(BPF_F_LOCK) should be EOPNOTSUPP. syscall.c takes care of unpinning the uptr. 2. The second update_elem(BPF_EXIST) fails. syscall.c takes care of unpinning the uptr. 3. The forth update_elem(BPF_NOEXIST) fails. bpf_local_storage_update takes care of unpinning the uptr.

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 reStructuredText 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.
