	<para>This parameter is only valid when the 
			<smbconfoption name="oplocks"/>
	parameter is turned on for a share. It allows the Samba administrator
	to selectively turn off the granting of oplocks on selected files that
	match a wildcarded list, similar to the wildcarded list used in the
	<smbconfoption name="veto files"/> 
	parameter.</para>


	<para>You might want to do this on files that you know will 
	be heavily contended for by clients. A good example of this 
	is in the NetBench SMB benchmark program, which causes heavy 
	client contention for files ending in <filename moreinfo="none">.SEM</filename>. 
	To cause Samba not to grant oplocks on these files you would use 
	the line (either in the [global] section or in the section for 
	the particular NetBench share :</para>

	<para>
	An example of use is:
<screen>
veto oplock files = /.*SEM/
</screen>
	</para>

<value type="default"><comment>No files are vetoed for oplock grants</comment></value>
