Re: [GIT PULL] Kselftest update for Linux 5.20-rc1

Hi,
This change breaks the Landlock test build when performed on the
tools/testing/selftests/landlock directory because the
(non-system/up-to-date) kernel headers aren't found. Looking at the use
of top_srcdir and HDR_PATH, it seems that multiple subsystems are using
this feature. I consider this change a regression.
It also removes the check on up-to-date kernel headers (thanks to the
Makefile's target timestamp).
I wasn't CCed for this change impacting Landlock [1]. Please keep in
mind to add at least maintainers and related mailing-lists for changes
on related subsystems.
The following patch almost revert commit a917dd94b832
("selftests/landlock: drop deprecated headers dependency") and partially
fixes commit 49de12ba06ef ("selftests: drop KSFT_KHDR_INSTALL make target"):

This doesn't fix the header timestamp check though.

Mickaël
