SYNOPSIS
       #include <keyutils.h>
       long keyctl_invalidate(key_serial_t key);

       diate removal from all the keyrings that point to it,  after  which  it

       function is called even if it is not yet fully dealt with.
       The caller must have search permission on a key to be able  to  invali-
       date it.

       be returned and errno will have been set to an appropriate error.
