The helper function bpf_sock_ops_cb_flags_set() can be used to both set and clear the sock_ops callback flags. However, its current behavior is not consistent. BPF program may clear a flag if more than one were set, or replace a flag with another one, but cannot clear all flags. This patch also updates the documentation to clarify the ability to clear flags of this helper function.

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.
