Caused by commit 0403c34571d1d (kunit: add tests for smp_cond_load_relaxed_timeout()) in that it's adding the new test which fails, I didn't investigate the quality of the test. I do note that there's some related functional work also from Ankur that's also added by the mm-nonmm-unstable tree but didn't investigate that either. I have used the version from next-20260506 instead, the code was in next-20260508 but I belive Thierry was emulating. --gt8IbS5oetCd5j/5 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmoK/0YACgkQJNaLcl1U h9DmlAf/SKNxtkLulpQJ5XY1mNUnaDzh+X1pfzpFu/3hG5IagEIH+LtmWQ5IP7qi fzKB5poR00vMXLN1B/MFhwscfv5RHdKQPL7Q1EYhzXhBogqw/doSUtIgYzjifYD5 FVlMeiGkvCjQz2KEAG4D1v5BvC1ZOoi5Em5V2LGsRsO/J1XqX1S7rIWeaAMHmu/Q +r19NEOnLu/Y+aeza4LZCvFtS50AsffEAu2lrTVe0XjltvNf7FxorPuHAK267oyB HlnI7rsC7qLUgcMDckj/Y9LQUSGG4uG8Q9QbvGraxdp/5+cgyVJrtZQIzoryO2g/ caWNiR7kmm0+y2oaLMeX5KGedDGNBQ== =3eHb -----END PGP SIGNATURE----- --gt8IbS5oetCd5j/5--
