From 2b8bc77817f45759346593eaedebaacddea05978 Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 18 May 2009 13:29:38 -0400 Subject: [PATCH] umount.nfs: Harden umount.nfs error reporting Add additional error reporting to nfs_advise_umount(). These messages can be displayed if the "-v" option is specified with umount.nfs. Normally these messages do not appear.
