From 9bce008bae8b57bc7b007bcc2071d1247a527120 Mon Sep 17 00:00:00 2001 From: Trond Myklebust <Trond.Myklebust@netapp.com> Date: Tue, 5 Jun 2012 18:32:03 -0400 Subject: NFS: Fix a commit bug The new commit code fails to copy the verifier into the wb_verf field of _all_ the nfs_page structures; it only copies it into the first entry. The consequence is that most requests end up failing to match in nfs_commit_release. Fix is to copy the verifier into the req->wb_verf field in nfs_write_completion.
