[NFS-Ganesha-Devel] Change in ffilz/nfs-ganesha[next]: Remove unused posix mount details when adding export if duplicate is ...

Sriram Patil has uploaded this change for review. ( https://review.gerrithub.io/436739 Change subject: Remove unused posix mount details when adding export if duplicate is found ...................................................................... Remove unused posix mount details when adding export if duplicate is found Ganesha maintains a list of mount points on the host to map the exports to a particular mount point. If the mount point is removed and remounted, the device id (st_dev) is supposed to change. A side effect of this mechanism is that, if a mount is removed (unmounted) from the system, ganesha still holds onto its details. If at a later point another mount is added which gets the same device id (stat.st_dev) as the old mount, ganesha detects the new mount as a duplicate file system. This change makes sure that, if the device id is reused and ganesha has old mount details in memory, we remove the old mount details if it is no longer mounted and exported by ganesha. If the device is reused, the old mount is definitely unmounted, so we just have to check that it is not being exported by ganesha to safely remove it.
