Subject: [PATCH] test: fix TEST-56-OOMD thresholds for linux 5.9 changes
|
|
|
834f04 |
|
|
|
834f04 |
Fixes #17533
|
|
|
834f04 |
|
|
|
834f04 |
The memory pressure values of the units in TEST-56-OOMD seemed to be a
|
|
|
834f04 |
lot lower after updating to linux 5.9. This is likely due to a fix from
|
|
|
834f04 |
https://github.com/torvalds/linux/commit/e22c6ed90aa91abc08f107344428ebb8c2629e98.
|
|
|

|
|
|

To account for this, I lowered memory.high on testbloat.service to
|
|
|
834f04 |
throttle it even more. This was enough to generate the 50%+ value to trigger
|
|
|
834f04 |
oomd for the test, but as an extra precaution I also lowered the oomd
|
|
|
834f04 |
threshold to 1% so it's certain to try and kill testbloat.service.
