From 819a9117354e22a26608ea31fd75e6eb13a15d8e Mon Sep 17 00:00:00 2001
From: Jeremy Allison <jra@samba.org>
Date: Wed, 1 Aug 2001 22:13:50 +0000
Subject: Added "strict allocate" per share parameter. This causes actual
 on-disk allocation to be done. Without it just does the ftruncate. Jeremy.
 (This used to be commit 0b052f103e82369088bc30724b86d8892c395cdb)
