    renameat(2): when retrying, check for pending signals
    
    The vn_start_write() call there is already interruptible.  Check for
    user signals before restarting due to ERELOOKUP, or after failed
    vn_start_write().  Note that vn_start_write(V_XSLEEP | V_PCATCH)
    does not check for signals if not sleeping.
