Hi Aurelien,
Thanks for the heads-up. I have a fairly comprehensive suite of various
OS test images I use for OpenBIOS testing and evidently not a single one
of them issues a TRIM command as I don't see any regressions here. Can
you point me towards the particular test image you are using?
ATB,
Mark.
