2.6.32-stable review patch. If anyone has any objections, please let us know.


From: Trond Myklebust <Trond.Myklebust(a)>

commit 82be934a59ff891cac598727e5a862ba2b9d1fac upstream.

If someone calls nfs_release_page(), we presumably already know that the
page is clean, however it may be holding an unstable write.
