Subject: NFS: Ensure we set NFS_CONTEXT_RESEND_WRITES when requeuing writes
From: Trond Myklebust <trond.myklebust@xxxxxxxxxxxxxxx>
commit c70701131f7a8edea91fc49d11796d342cff7c62 upstream.
If a write attempt fails, and the write is queued up for resending to
the server, as opposed to being dropped, then we need to set the
appropriate flag so that nfs_file_fsync() does the right thing.
