From 5326de9e94bedcf7366e7e7625d4deb8c1f1ca8a Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 13 Nov 2019 09:39:36 +0100 Subject: [PATCH] NFSv4.x: Drop the slot if nfs4_delegreturn_prepare waits for layoutreturn If nfs4_delegreturn_prepare needs to wait for a layoutreturn to complete then make sure we drop the sequence slot if we hold it.
