Presumably other builds include mm_types.h indirectly. I have used the folio tree from next-20211224 for today. --=20 Cheers, Stephen Rothwell --Sig_/jiUas6EpUPf7oy=aeGL6jnH Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmHT91UACgkQAVBC80lX 0Gz/VAf5AQ2ft9hJ59Aqy5TN24eHmPgPM8FyqiVenW4jk5ma2BiWJIaaQ6I6tgC5 Trs85AIiKgEjajPfjgvcIeOqxdV4kVD20Ka+ZXTGnM5GQr6x0F3etKmmk/ZwRTwE x0WJa7onjADcdyZyvorR4tj9XdqC8gIjO7DA3DHCIMUYSorV8J+NwK7jeRNdAMBu F4hOsOpW7o2P+vW8NP9/6wnrWbZ+JRCPRlLxRfQmSdMqd2iGUVZAi28FFbqE1ReG r9rH/mb7yZ/klMi5QjJ5cBbB1QYbve/OzbsAVxcGQv3CLH+QXJhexJ9KxQ8YLIUH O45QBZ2zNiivo/2sBDGHA1EW9NjP1w== =sFJK -----END PGP SIGNATURE----- --Sig_/jiUas6EpUPf7oy=aeGL6jnH--
