Though this patch fixes the crash. Bigger question is how did loc->parent
happen to contain "samba2". The rename is done in root directory and hence if
there is a lookup on ".samba2", loc->parent should've been root.

1. We need more information on smb traffic during the test
2. Probably there is a bug in higher layers (smb-server, gfapi, smb-client etc)
which fill wrong loc->parent (not ruling out dht is not modifying loc->parent,
but highly unlikely).

regards,
Raghavendra
