From 70b9ecbdb9c5fdc731f8780bffd45d9519020c4a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Tue, 3 Jan 2006 09:55:34 +0100 Subject: NFS: Make stat() return updated mtimes after a write() The SuS states that a call to write() will cause mtime to be updated on the file. In order to satisfy that requirement, we need to flush out any cached writes in nfs_getattr(). Speed things up slightly by not committing the writes.
