  Except Kconfig and Makefile, all source files for UDF filesystem doesn't
bear SPDX license identifier. Add appropriate license identifier while
replacing boilerplates.

tglx, in your patch attempt [1] you said that you'd figured out original
author names in UDF source files [2], but you had not already try to
contact them, right? I thought that they are pseudonyms if they couldn't
be contacted.

This is not BSD-2-Clause. Ignoring the interior statement about the
GPL, I think the closest SPDX identifier might be
https://spdx.org/licenses/BSD-Source-Code.html
but it doesn't quite match.

Same comment - this is not BSD-2-Clause.

Shouldn't this be
// SPDX-License-Identifier: LGPL-2.0-or-later ?
(or are you implicitly using the obscure LGPLv2.x section ... 3 mechanism?)

BSD-2-Clause but the second clause is the third one on BSD-3-Clause.

That's right. I missed the exact notice above when I submitted this

Please, dot not do this. It is really rude to people who worked on it in
past (even if they do not care about this particular file anymore) as
technically they still have ownership of this code / file. And such
change never remove their ownership or copyright in most countries.

Yes, copyright lines should never be removed.

Bagas, I recommend taking the Linux Foundation "copyright and licensing"
online course before you respin this series.  It's free online and might
help you in understanding some of the issues involved here and prevent
you from making these types of mistakes in the future.
