+    <para>This parameter controls whether Samba honors a request
+    from an SMB client to ensure any outstanding operating system
+    buffer contents held in memory are safely written onto stable
+    storage on disk. If set to <constant>yes</constant>, which is
+    the default, then Windows applications can force the smbd server
+    to synchronize unwritten data onto the disk. If set to
+    <constant>no</constant> then smbd will ignore client
+    requests to synchronize unwritten data onto stable storage on
+    disk.</para>
+
+    <para>In Samba 4.7.0, the default for this parameter changed from
+    <constant>no</constant> to <constant>yes</constant> to better
+    match the expectations of SMB2/3 clients and improve application
+    safety when running against smbd.</para>
+
+    <para>The flush request from SMB2/3 clients is handled
+    asynchronously inside smbd, so leaving the parameter as the default
+    value of <constant>yes</constant> does not block the processing of
+    other requests to the smbd process.</para>
+
+    <para>Legacy Windows applications (such as the Windows 98 explorer
+    shell) seemed to confuse writing buffer contents to the operating
+    system with synchronously writing outstanding data onto stable storage
+    on disk. Changing this parameter to <constant>no</constant> means that
+    <citerefentry><refentrytitle>smbd</refentrytitle>
+    <manvolnum>8</manvolnum></citerefentry> will ignore the Windows
+    applications request to synchronize unwritten data onto disk. Only
+    consider changing this if smbd is serving obsolete SMB1 Windows clients
+    prior to Windows XP (Windows 98 and below). There should be no need to
+    change this setting for normal operations.</para>
