What we were hoping for was that you would merge together the vfs, iomap, and various fs-specific trees (e.g., bcachefs, btrfs, ext4, f2fs, xfs, etc.) together, and then publish it as "fs-next". You could then use fs-next as something that would be merged into linux-next instead of the component fs trees, so hopefully it wouldn't be a significant amount of extra work for you. As Willy stated, the advantages of having an official daily "fs-next" tree is that multiple file system developers would be able to test the same branch and compare notes when regressions are found. And the advantage of fs-next versus the full linux-next is that it reduces the chances of tests getting blocked by non-fs-relevant changes. Cheers, - Ted
