From a6ae5d3a2ed313eee8aabece5c8d8347f4db7baf Mon Sep 17 00:00:00 2001 From: Tiago Gasiba Date: Wed, 29 Oct 2025 21:09:39 +0100 Subject: [PATCH] truss: Properly display first argument to nmount The first argument to nmount(2) is an nvlist in the form of an iovec, which truss already knows how to decode. Set the correct flag so this happens automatically.
