That same hash.h is also part of fio, and the original commit there has a Signed-off-by line: https://git.kernel.org/pub/scm/linux/kernel/git/axboe/fio.git/commit/hash.h?id=bdc7211e190482f0c17c109a0d90834a6611be1c Also Debian themselves say that it is GPL-2+ (and copyrighted by William Lee Irwin III): https://metadata.ftp-master.debian.org/changelogs/main/f/fio/fio_3.12-2_copyright

The file he committed has not any reference to the license. > [fio] > https://metadata.ftp-master.debian.org/changelogs/main/f/fio/fio_3.12-2_copyright I'm afraid that this entry in wrong. I'll seek confirmation with Martin Steigerwald. Regards, Domenico
