From 66c7d4caf52cf4f0b6ce4301e91268010d7fbcda Mon Sep 17 00:00:00 2001 From: Brian Behlendorf Date: Fri, 23 Feb 2018 16:19:41 -0800 Subject: [PATCH] Fix more cstyle warnings This patch contains no functional changes. It is solely intended to resolve cstyle warnings in order to facilitate moving the spl source code in to the zfs repository.
