    fix bogus path_put() of nd->root after some unlazy_walk() failures · d870b4a1
    Al Viro authored Nov 29, 2013
    
    
    Failure to grab reference to parent dentry should go through the
    same cleanup as nd->seq mismatch.  As it is, we might end up with
    caller thinking it needs to path_put() nd->root, with obvious
    nasty results once we'd hit that bug enough times to drive the
    refcount of root dentry all the way to zero...
