I've never seen that change go past on a public list... > https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git xfs-5.20-merge Oh, it's in a developer's working tree, not something that has been proposed for review let alone been merged. So why is this report being sent to lkml, linux-xfs, etc as if it was a change merged into an upstream tree rather than just the developer who owns the tree the commit is in? -Dave. -- Dave Chinner david@fromorbit.com
