From a400ef50e78554c779742d45c6f7bfa4fa39d990 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 17 Jun 2015 19:56:22 -0400 Subject: [PATCH] NFS: Ensure we set NFS_CONTEXT_RESEND_WRITES when requeuing writes 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.
