The license itself is here. It is standard MIT license. The original text for the above paragraph is clearer about that: "The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software." The "next paragraph", mentioned on this variant: > > > - > > > -THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS > > > -OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF > > > -MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. > > > -IN NO EVENT SHALL THE AUTHOR > > Missing "Authors or copyright holders" Is actually a disclaimer's note, and not the license itself, informing that there's no warranties provide by author(s). With SPDX, this will point to LICENSES/preferred/MIT with has a paragraph that fits to the same purpose: it excludes any express or implied warranties. Btw, the Kernel itself had this at COPYING by the time this was added and before SPDX, which was there when this code was added. This is part of the GPL text: This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. So, I can't see any changes here: with or without this patch, there's no warranties from the ones that wrote the code - nor for any copyright holders - as the Kernel as a hole is released under GPL. Also, LICENSES/preferred/MIT define that MIT license text is: MIT License Copyright (c) <year> <copyright holders> In this specific case, "Copyright © 2006 Dave Airlie", which is both the author and the copyright holder that is part of MIT, so the text meaning is identical with either "AUTHOR" or "AUTHORS OR COPYRIGHT HOLDERS" is used. So, I can't see any difference from legal standpoint. Regards, Mauro
