    Phoronix: XFS Metadata Corruption On Linux 6.3 Tracked Down To One Missing One-Line Patch

    Last week XFS users began encountering metadata corruption on the latest Linux 6.3 point releases. Following kernel developers and those testing the kernels on affected hardware over the US holiday weekend, it's believed the issue has been tracked down to one missing patch that is a one line of code being deleted...

    Then it would appear I was right, this would not have affected any LTS kernels. If I'm reading it right, it was an attempt to fix a different bug with the patch deletion in the 6.3 kernel.

        Ah, yes, so we can have the filesystem corrupt itself on ALL kernel versions.

          This smells suspiciously like a "magic fix." Hopefully there's more investigation later to ensure that it's complete and correct.

                I agree that XFS is more stable than BRTFS, but the only time I experimented corruption with BTRFS was due to faulty RAM and still recoverable easily without significant data loss.

                  No official LTS kernel was impacted (although some people/distros backport the most interesting things to their own LTS kernels), as the bug was introduced in the 6.3 cycle. The 6.3 stable series, obviously, was impacted. The fix was introduced in the 6.4 development timeframe to address a completely different issue, but, as it turns out, was more important than first realized (had the impact been understood at the time the patch was made I am sure it would have been marked for stable at that time).

                    Ahh, I see now, that makes more sense. So they were wondering why the 6.4 kernel did not have the same problem and found this line for this completely different bug fix was also unknowingly fixing the xfs metadata corruption problem in 6.3.
