From 7be7b3ca16a59b8335ef2877f4696cf74f646d20 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 4 Jul 2018 21:01:16 -0400 Subject: [PATCH] NFS: Ensure we immediately start writeback on rescheduled writes If the writes are being rescheduled due to a pNFS error, then we really want to immediately start a new flush. The O_DIRECT code already does this, so we only need to worry about buffered writes.
