From 7e20694d91f817f8e9f62404aca793ae0df4d98a Mon Sep 17 00:00:00 2001 From: David Chinner Date: Thu, 17 Apr 2008 16:49:55 +1000 Subject: [XFS] Remove periodic logging of in-core superblock counters. xfssyncd triggers the logging of superblock counters every 30s if the filesystem is made with lazy-count=1. This will prevent disks from idling and spinning down as there will be a log write every 30s. With the way counter recovery works for lazy-count=1, this code is unnecessary and provides no real benefit, so just remove it.
