Title:
arm64 atomic issues cause disk corruption
Status in linux package in Ubuntu:
Invalid
Status in linux source package in Mantic:
Fix Released
Bug description:
SRU Justification:
[Impact]
The mantic kernel introduced a regression in atomic operations on arm64
which causes all kinds of problems including file system corruptions,
since commit "locking/atomic: scripts: restructure fallback
ifdeffery".
An example report of people encountering this in UTM with a arm64
generic kernel: https://github.com/utmapp/UTM/issues/4840
[Fix]
Cherry-pick commit "locking/atomic: scripts: fix fallback ifdeffery"
from linux-stable v6.5.6
[Test Plan]
Boot test on an arm64 vm.
[Where problems could occur]
Since this is touching atomic operations, this has a wide impact on the
kernel.
