From eb55338ccdc000feac92118553c5ce59bed87fa8 Mon Sep 17 00:00:00 2001 From: David Disseldorp Date: Wed, 26 Jan 2011 14:32:01 -0800 Subject: [PATCH] Looking into printer driver issues, I ran across some peculiarities in copy_file(): - Firstly, if the source file is zero bytes, NT_STATUS_DISK_FULL is returned. - Secondly, the conditional lseek is confusing. It fires when OPENX_FILE_EXISTS_OPEN is set and I can't see why the lseek is necessary in this case. - Finally, the lseek error path also results in NT_STATUS_DISK_FULL. Proposed fix for first and third point below.
