From bb346f63976823c2959b0c5917928f12cbf96e4a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Thu, 20 Sep 2012 15:52:13 -0400 Subject: [PATCH] NFSv4.1: reset the inode MDS threshold counters on layout destruction Instead of resetting the inode MDS threshold counters when we mark the layout for destruction, do it as part of freeing the layout.
