From 12e49aa48b677c67cb9621ef508995aad63065f1 Mon Sep 17 00:00:00 2001 From: Mark Johnston Date: Fri, 29 Dec 2023 12:56:35 -0500 Subject: [PATCH] spa: Let spa_taskq_param_get()'s addition of a newline be optional For FreeBSD sysctls, we don't want the extra newline, since the sysctl(8) utility will format strings appropriately.
