That helped, it brought down the test failures from 261 to 170 with a
success rate improvement from 55.4% to 57.9%.

Dashboards for both results, the old one:

https://kdevops.org/ext4/v6.15-rc2-a74831cc.html

The latest one:

https://kdevops.org/ext4/v6.15-rc2.html

Detailed test results:

https://github.com/linux-kdevops/kdevops-results-archive/commit/a051dea3db9fcc7e164c1d027264e181b68833e0

And so the new file name for results is

fstests/gh/linux-ext4-kpd/20250417/0001/linux-6-15-rc2/8ffd015db85f.xz
