This is due to a conflict with the preexisting wait_for_pid() in pidfd.h triggered by: 32f54f2bbccfd (selftests/filesystems: add tests for empty mount namespaces) I am continuing to use the tree from next-20260312. --byGRgxhCMrP/HDhs Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmnD1dYACgkQJNaLcl1U h9DmkAf/Vc6VoihCeS1SzehwsS32ILROv2DvtMORgoAkRbBFzoRNYapvC9bRJY+D 8LQXVAn2k5/5Vl9upngjS9N3FLRKaFxkjyIRlvSqM1tJccssK9F17PdrAxJe1XDX sDW1AF9cBMlxt9TRxdIGhin6ixOibIjKCPP1wRRWxUXCGZ2EqMN4vXVk7uVGptfF wqMw9S0dhUHt4WnVUIn7S7awKDE8152oE0v5YQmy3FIOBkTurFNS2+x7mhenUQkX FaO3zqewZkU8wr1VJBoxWHM4g8TjNtt8foApoTi8DnWbZYIub6YSzv5tNJsZgTgE QhmutA0VGePyqN7Se3OeGgxYNN5VOg== =ZI2B -----END PGP SIGNATURE----- --byGRgxhCMrP/HDhs--
