+ <title>DESCRIPTION</title>
+
+ <para>This VFS module is part of the
+ <citerefentry><refentrytitle>samba</refentrytitle>
+ <manvolnum>7</manvolnum></citerefentry> suite.</para>
+
+ <para>The <command>vfs_commit</command> VFS module keeps track of
+ the amount of data written to a file and synchronizes it to
+ disk when a specified amount accumulates.
+ </para>
+
+ <para><command>vfs_commit</command> is useful in two
+ circumstances. First, if you have very precious data, the
+ impact of unexpected power loss can be minimized by a small
+ commit:dthresh value. Secondly, write performance can be
+ improved on some systems by flushing file data early and at
+ regular intervals.</para>
+
+ <para>This module is stackable.</para>
