>From a7d2b2bdc9a0b55d5b08e15756c7e65c48c4bca5 Mon Sep 17 00:00:00 2001 From: Wendy Cheng <wcheng@redhat.com> Date: Fri, 23 Feb 2007 00:21:17 -0500 Subject: [PATCH] [GFS2] NFS filehandle check
File handle checking error found in '07 NFS connectathon. The fh_type and fh_len are not necessarily identical. Some of the client machines could fail mount with stale filehandle without this patch.
