Re: [PATCH] selftests/exec: add missing SPDX-License-Identifier tag

Thank you for the correction and the link.
I compared the license text in recursion-depth.c with
/linux/LICENSES/preferred, the BSD-2-Clause or BSD-3-Clause which use
"Redistribution and use in source and binary" while this file uses
"Permission to use, copy"
I wanted to confirm which SPDX identifier is correct for this OpenBSD
license, before sending a v2 as I do not see separate OpenBSD entry
under LICENSES/ directory.

I also noticed the same text in various other files under
tools/testing/selftests, should I address those in the same patch
series?

Thanks again.
