+Subject: [PATCH 7/9] Refactor openzfs_sysctl_init() and ZfsArcMeter...
+
+openzfs_sysctl_init() now returns void instead of int.
+The ZfsArcStats->enabled flag is set inside the init function
+now, instead of having to be set from its return value.
+Preparation for more flag setting in Compressed ARC commit.
+
+ZfsArcMeter_readStats() added and all Meter->values[] setting
+moved to it, eliminating duplicated code in
+{darwin,freebsd,linux,solaris}/Platform.c.
