    vfs: add lookup_hash() helper · 3c9fe8cd
    Miklos Szeredi authored
    Overlayfs needs lookup without inode_permission() and already has the name
    hash (in form of dentry->d_name on overlayfs dentry).  It also doesn't
    support filesystems with d_op->d_hash() so basically it only needs
    the actual hashed lookup from lookup_one_len_unlocked()
    
    So add a new helper that does unlocked lookup of a hashed name.
