The guest-agent sets the I/O scheduler to 'none', causing errors such as below: ``` 2024-10-07T09:24:03.262548+00:00 oracular-old-gga-test google_guest_agent[1125]: panic: invalid return from write: got 256 from a write of 4 ``` With strace, we can also see that the return value of write is unexpected: [pid 3127] write(7, "none", 4) = 256 This is breaking provision of GCP cloud images, so bump it to Critical. [Fix] Fix commit is e3accac1a976e65491a9b9fba82ce8ddbd3d2389 ("block: Fix elv_iosched_local_module handling of "none" scheduler"). [How to test] Apply the fix, rebuild the kernel and try to change scheduler in sysfs, e.g.: # echo "none" > /sys/devices/virtual/block/loop1/queue/scheduler # echo $? 0 [Regression potential] Upstream clean cherry-pick, already part of v6.11.2.
