(Cheers to the mutual dissatisfaction.)

So, a couple of questions: Have you done a trial merge with a current linux-next tree to see what sort of mess/pain we may already be in? Is it all stable enough now that it could be sent as a patch series for Andrew to include in mmotm (with perhaps just smallish followup patches)? --=20 Cheers, Stephen Rothwell --Sig_/vv2ccmDjANVQ_zxEAVutc2L Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAmJOoVEACgkQAVBC80lX 0GzE3Qf5AQTCVeynkAsn3+qk9evNVsNw+dWxlovauW3+RjhUcon2308Q6aN7oSPw fex528YIkIZ5WBjpCvTqt2qy/wsUfN01Terj/MrmC1NVIWSVdQxQo1xydTpbwRym aKXyxU4rcp1o17/P65KZsISf0KXPXFKnLdPAKs5wEbgD6at5eohehdsGYCWk9hnX 1f/rEP51PEmxl9AE91SbpTvw3Mj5uKz282I3mUJiqQaIDPcNbPv6qM9RLKRYa9Kn IOdqR6+UvqVE0BLoi0Q3ikCuC7RI3wSuAsDlKhLL7QtlbRDjKbAT/qTxo408JScg pPI07lXejPErRWE6+HSo4yLiLW9+iQ== =mvXT -----END PGP SIGNATURE----- --Sig_/vv2ccmDjANVQ_zxEAVutc2L--
