nfs: strip trailing / when clients do subdir mounts
Mounting a volume over NFS with a subdir followed by a / does not work:
# mount -t nfs -o vers=3 storage.example.com:/media/installation/ /mnt
mount.nfs: an incorrect mount option was specified
In the nfs.log:
[client-rpc-fops.c:2930:client3_3_lookup_cbk] 0-media-client-0: remote operation failed. Path: /installation/ (00000000-0000-0000-0000-000000000000) [Invalid argument]
[client-rpc-fops.c:2930:client3_3_lookup_cbk] 0-media-client-1: remote operation failed. Path: /installation/ (00000000-0000-0000-0000-000000000000) [Invalid argument]
[mount3.c:1134:mnt3_resolve_subdir_cbk] 0-nfs: path=/installation/ (Invalid argument) [Invalid argument]
It is not possible to resolve paths with a trailing /. Stripping
trailing /'s from the subdir to mount is sufficient to make it work
again.
