From ba6a46a03f3c46ed68be551c722161bb37caf095 Mon Sep 17 00:00:00 2001 From: Steve French Date: Mon, 26 Feb 2007 20:06:29 +0000 Subject: [PATCH] [CIFS] small piece missing from previous patch There were two i_size_writes in the new truncate function - we missed one in the last patch. Noticed by Shaggy when he reviewed. Thank you Shaggy ...
