No, sorry, i've posted two 'trim/discard' topic that (apart this) are
totally unrelated.
I'm speaking now of host OS, eg PVE: if i have an SSD-based ZFS pool, how
can i trim it?
Seems that recent 'zfsutils-linux' package add some 'framework' to do trim,
but seems (totally) undocumented. So i'm seeking feedback.
I hope i was clear now...
