This patchset fixes up some cache invalidation problems that can occur when cache=loose. The main point is to ensure that we revalidate the cache prior to satisfying a read.
At the same time, I added a fix for a potential problem that cropped up with NFS a while back, and to which CIFS is also vulnerable. This was originally reported by Tetsuo Handa, and as far as I can tell this fixes his testcase, assuming that you also ensure that kernel oplocks are enabled.
