Hi Tom,
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/lib/xxhash.c?h=v5.1-rc7&id=5d2405227a9eaea48e8cc95756a06d407b11f141
this is the only commit in the kernel touching the xxhash sources. The
author only says this:

I think we can add SPDX tags to both xxhash and zstd sources. Do you
agree? Shall I post v2?
