From 59a5507df986d27db7cd38fcd8be5d94eff0fa39 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Fri, 3 Aug 2007 13:23:39 -0400 Subject: [PATCH] mount.nfs: umount needs to pick up transport option from /etc/mtab Now that umount's default transport protocol has become more flexible, it will need to detect both proto=udp and proto=tcp in /etc/mtab.
