Bug#940105: linux: serious corruption issue with btrfs

Show all headers | View raw

Source: linux
Version: 5.2.9-2
Severity: critical
Tags: upstream patch
Justification: causes serious data loss


Hi.

There were some reports over the last weeks from users on linux-btrfs which
suffered from catastrophic btrfs corruption.
The bug which is apparently a regression introduced in 5.2 has now been found[0]
an a patch is available[1].

Since it's unclear how long it will take to be part of a stable release and when
Debian will pick this up in unstable, please consider to cherry-pick the patch.

Thanks,
Chris.
