First seen on commit sha id c12cd257292c0c29463aa305967e64fc31a514d8. Good: 7ff71d62bdc4828b0917c97eb6caebe5f4c07220 Bad: c12cd257292c0c29463aa305967e64fc31a514d8 (not able to fetch these ^ commit ids now)
The problem was in the slab tree not fs, sorry for the noise: https://lore.kernel.org/all/52be272d-009b-477b-9929-564f75208168%40suse.cz
The reported regressions have been fixed in latest commits on the sashal/linus-next.git tree.
