Subject: [PATCH 10/11] nfs: set FILE_CREATED

From: Miklos Szeredi <mszeredi@...e.cz>

Set FILE_CREATED on O_CREAT|O_EXCL.  If the NFS server honored our request
for exclusivity then this must be correct.

Currently this is a no-op, since the VFS sets FILE_CREATED anyway.  The
next patch will, however, require this flag to be always set by
filesystems.
