Thanks, It is silly, if it's really safe to say that Btrfs won't be the default file system in any release blocking deliverable. Having blocker status was always a means to that end. But right now it's maybe three (?) automated tests that depend on Btrfs working. If Fedora Workstation defaulted to Btrfs, that's dozens or even hundreds of tests? Adam? Bug fix was merged in rc2. The patch on linux-btrfs@ 25 Jul 2019 11:27:29 +0300 which is just before kernel-5.3.0-0.rc1.git3.1.fc31, 2019-07-25 21:01:20 Plausibly it was in all rc0 and rc1 kernels. What if this deadlock were happening in ext4 for all rc0 and rc1 kernels? What questions get asked? How did the bug not get caught by xfstests before it got into linux-next? Does anyone pop a gasket on lkml? Is this just a weird sometimes it happens rarely kind of thing? I don't know the exact nature of the bug, which goes to the kernel team's point that someone who does know needs to tell them the autopsy summary so they can really assess the default fs question. And another question for QA. If it were Btrfs by default for Workstation, would you just convert all the tests that rely only on ext4 now to Btrfs? Or duplicate those tests so you can run them in parallel? How much more testing is that and what's the impact on time and resources? -- Chris Murphy _______________________________________________ kernel mailing list -- kernel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to kernel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/kernel@xxxxxxxxxxxxxxxxxxxxxxx
