Hi,
This bug still exists on 12.2 but not anymore en 13.0 even with autotrim
enabled and vfs.zfs.vdev.trim_max_active=2 by default on 13.0 .
I got about the same performance (maybe a little better) with
13.0/autotrim=on/trim_max_active=2 than with 12.2/(autotrim implicit and always
on before 13 )/trim_max_active=2000
It looks like openzfs trim strategy is different that previous one and more
efficient.
