Given that the commit message for this commit includes "Very much a demo for now, downstream only." it should *not* be in linux-next. It should especially not have turned up at this point (just before the merge window). I also wonder about some of the other commits in that tree :-( I have reverted that commit for today. --=20 Cheers, Stephen Rothwell sfr@canb.auug.org.au --Sig_/XIFIOUyne=bMPmS4hGpceDy Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAEBCAAGBQJTjYmUAAoJEMDTa8Ir7ZwVaeYP/39TUaRmZPeji4jNcBB3A/Kr Shjme09bff6NpDochHbQHVxkB9zB1vynkZfSXv3/+tQRjSZQyXBAK4sVkuKn21wy NZVgJCaiJY6tExtrVVvqR83J5IfM5m0/loEFkMafD4qeo1oQY8rx8YY6DVOQCavP a5BdZ+tpBR7Lhsr6igZ7j8qjXkFVzUMYnbeLBlqvgnoxvnByUJRSYumMQzGVrE0m J1mLRMy332xro2WxVrqQMHQ974sIMbabnbfQ0/RTdLDBwH7tKUJvUr7AAmcEz/I4 OZlEDqfupIgvasaUr9R4iOyxaX3HvQVeuyQJBviI51/AMIMA5/oaVVwn50Kp9Mp6 40O1YFYiZljtv2P96INBDZpzf6Am5hxR/yKDdBRR8eQE1llfmOKfCjbRlIjKV9Ct bgRxwXe93QMMtWT+Cx1roW/DqW5CxyHHFY0knie86ORxpYjoSKlAGssxVe/Ii1lq fMXKDVOfBFchciHJoZpRtn7MHofQuzRaxvXlqoxA7fEDYl8TsI2sBgZE9DsJTipX s+i8VRea5CgadU/uCrtxbrdWlmQJzA0WWX8eVWueUDTsqQ1NPdbx4UBRqZS9iwgk dxRuke0DW8bBwUFDR0UoD/4FwPDeyuTICTj8KikbOYr012S3hsmRTffyxnZgI7pW YxJ0WScEdT5a3AWVvGqX =aXTH -----END PGP SIGNATURE----- --Sig_/XIFIOUyne=bMPmS4hGpceDy--
