[HPDD-discuss] lustre_dlm_flags.h GPLv3 license clarification

Greetings, Resending this using the correct version of get_maintainers.pl. As recommended in the thread "SPDX-License-Identifier” [1], I would like to followup with the maintainers of the file drivers/staging/lustre/lustre/include/lustre_dlm_flags.h regarding the GPLv3 license statement contained in that file [2]. Is there an GPLv3 exception clause which can be applied for this file similar to the bison exception clause or is this file licensed only under GPLv3 only in which case it would appear to be incompatible with the Linux kernel license [3]? TIA! — Regards, George [1] https://lkml.org/lkml/2015/2/5/65 [2] https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/driv...
