Subject: [PATCH 03/18] orangefs: do not invalidate attributes on inode create

From: Martin Brandenburg <martin@...ibond.com>

When an inode is created, we fetch attributes from the server.  There is
no need to turn around and invalidate them.

No need to initialize attributes after the getattr either.  Either we'll
do nothing or do something wrong.
