Subject: [PATCH] fs-backend: fix FD allocation for file creation
Date: Fri, 25 Jul 2008 09:43:07 +0100 [thread overview]
Message-ID: <20080725084307.GG4482@implementation.uk.xensource.com> (raw)
fs-backend: fix FD allocation for file creation
The creation operation also opens a file, we need to allocate a virtual
fd for that too.
