Subject: [PATCH] Filesystem: fix getting the wrong block device when doing
 grep

If we have such a filesystem structure mounted in our cluster
/dev/drbd50     /export/prq/upgrade_emspq       xfs
/dev/drbd55     /export/prq/upgrade_sharedmsb   xfs
/dev/drbd1      /export/devAGN/share    xfs
/dev/drbd5      /export/dev/archivesn1agn       xfs

When we want to stop the filesystem mounted on
/export/dev/archivesn1agn, we probably will get the wrong entry returned
here and thus will try to stop the wrong target.
