Revision 592025a03b34927f35852058c933ffcd7c500321 authored by Jacob Keller on 14 November 2019, 18:45:01 UTC, committed by David S. Miller on 15 November 2019, 20:48:32 UTC
Fix the renesas PTP support to explicitly reject any future flags that get added to the external timestamp request ioctl. In order to maintain currently functioning code, this patch accepts all three current flags. This is because the PTP_RISING_EDGE and PTP_FALLING_EDGE flags have unclear semantics and each driver seems to have interpreted them slightly differently.

README
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.
