docs: def remove(release):
      '''
      Remove a specific version of the kernel.
  
      release
          The release number of an installed kernel. This must be the entire release
          number as returned by :py:func:`~salt.modules.kernelpkg_linux_yum.list_installed`,
          not the package name.
  
      CLI Example:
  
      .. code-block:: bash
  
          salt '*' kernelpkg.remove 3.10.0-327.el7
