commit 710765a87d599d95de51b79202ba3d82fd03ed95
Author: Steve Dickson <steved@redhat.com>
Date: Wed Jun 25 09:23:45 2008 -0400
When a FQDN exists in /var/lib/nfs/rmtab it causes
the exportfs command to seg fault due to the nfs_export pointer
not being allocated. Reworking the parentheses in rmtab_read()
so the htype variable is evaluated correctly fix the problem.
