From b0b342201140530c5b9e00408f12d22258df7c4e Mon Sep 17 00:00:00 2001 From: NeilBrown Date: Mon, 6 Aug 2012 08:41:13 -0400 Subject: [PATCH] umount: use correct return value for is_vers4. is_vers4 in mount_libmount.c is based on nfs_umount_is_vers4 in nfsumount.c, except the return values are reversed. The result of this is: - a MOUNT_UMNT call is not sent when an NFSv3 or NFSv2 filesystem is unmounted - a MOUNT_UMNT call *is* sent when and 'nfs4' filesystem is unmounted (but not when an 'nfs -o vers=4 filesystem is unmounted, as that is checked elsewhere).
