    ovl: fix regression in fsnotify of overlay merge dir · 2aed489d
    Amir Goldstein authored
    A re-factoring patch in NFS export series has passed the wrong argument
    to ovl_get_inode() causing a regression in the very recent fix to
    fsnotify of overlay merge dir.
    
    The regression has caused merge directory inodes to be hashed by upper
    instead of lower real inode, when NFS export and directory indexing is
    disabled. That caused an inotify watch to become obsolete after directory
    copy up and drop caches.
    
    LTP test inotify07 was improved to catch this regression.
    The regression also caused multiple redirect dirs to same origin not to
    be detected on lookup with NFS export disabled. An xfstest was added to
    cover this case.
