From cb380909ae3b1ebf14d6a455a4f92d7916d790cb Mon Sep 17 00:00:00 2001 From: Keith Busch Date: Thu, 27 Feb 2025 15:06:30 -0800 Subject: vhost: return task creation error instead of NULL Lets callers distinguish why the vhost task creation failed. No one currently cares why it failed, so no real runtime change from this patch, but that will not be the case for long.
