Date: Mon, 21 Sep 2020 17:14:13 +0300 Message-ID: <4972578.pTZnC5dHRY@walnut> Hi, I wanted to know why the "issue_discards" setting isn't enabled by default. Are there any dangers in enabling it or if not is there a chance of getting the default changed? Also it's not entirely clear to me if/how "issue_discards" affects thin pool discard passdown. --nextPart3127830.BPv24sfAYc Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
