Let me try clarifying this further, how about: copyleft-next-0.3.1 is explicitly compatible with GPLv2 (or later) and can therefore be used for kernel code. Despite this, if you use copyleft-next-0.3.1 on Linux, the recommended practice is to express dual licensing with GPL using in the SPDX license identifiers by using by the OR operator. > > + To use the copyleft-next-0.3.1 license put the following SPDX tag/value > > + pair into a comment according to the placement guidelines in the > > + licensing rules documentation: > > + SPDX-License-Identifier: GPL-2.0 OR copyleft-next-0.3.1 > > + SPDX-License-Identifier: GPL-2.0-only OR copyleft-next 0.3.1 > > + SPDX-License-Identifier: GPL-2.0+ OR copyleft-next-0.3.1 > > + SPDX-License-Identifier: GPL-2.0-or-later OR copyleft-next-0.3.1 > > Please don't propagate the GPL-2.0 and GPL-2.0+ tags.

OK thanks for the recommendation, I'll leave it at: + SPDX-License-Identifier: GPL-2.0 OR copyleft-next-0.3.1 + SPDX-License-Identifier: GPL-2.0-or-later OR copyleft-next-0.3.1 Luis
