[PATCH 2/2] NFS: Ensure we set NFS_CONTEXT_RESEND_WRITES when requeuing writes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
