<para>For UNIXes that support kernel based <link linkend="OPLOCKS">
<parameter moreinfo="none">oplocks</parameter></link>
(currently only IRIX and the Linux 2.4 kernel), this parameter
allows the use of them to be turned on or off.</para>
<para>Kernel oplocks support allows Samba <parameter moreinfo="none">oplocks
</parameter> to be broken whenever a local UNIX process or NFS operation
accesses a file that <citerefentry><refentrytitle>smbd</refentrytitle>
<manvolnum>8</manvolnum></citerefentry> has oplocked. This allows complete
data consistency between SMB/CIFS, NFS and local file access (and is
a <emphasis>very</emphasis> cool feature :-).</para>
<para>This parameter defaults to <constant>on</constant>, but is translated
to a no-op on systems that no not have the necessary kernel support.
You should never need to touch this parameter.</para>
