<para> The capability can only be enabled as a result of direct root system administrator action. To further prevent accidental usage, the capability is disabled unless <parameter>unprotected_address_space=1</parameter> is specified as an option for the module in the <filename>grub.conf</filename> file. If the <filename>rmem.ko</filename> kernel module is explicitly loaded, the kernel will have a <parameter>tainted</parameter> flag. In this case, Red Hat Global Support may require you to reproduce any problems without the presence of <filename>rmem.ko</filename>. </para> LKB |
