    cifs: demote cERROR in build_path_from_dentry to cFYI · fa71f447
    Jeff Layton authored
    Running the cthon tests on a recent kernel caused this message to pop
    occasionally:
    
        CIFS VFS: did not end path lookup where expected namelen is 0
    
    Some added debugging showed that namelen and dfsplen were both 0 when
    this occurred. That means that the read_seqretry returned true.
    
    Assuming that the comment inside the if statement is true, this should
    be harmless and just means that we raced with a rename. If that is the
    case, then there's no need for alarm and we can demote this to cFYI.
    
    While we're at it, print the dfsplen too so that we can see what
    happened here if the message pops during debugging.
