Will be used by the following patch to avoid code duplication. No functional changes intended. The only difference is that now flow_limit_cpu_sysctl() will always compute the flow limit mask on each read operation, even when read() will not return any byte to user-space. Note that the new helper is placed under a new #ifdef at the file start to better fit the usage in the later patch Signed-off-by: Paolo Abeni <pabeni@redhat.com> Reviewed-by: Simon Horman <simon.horman@corigine.com> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
