From 924491f2e476f7234d722b24171a4daff61bbe13 Mon Sep 17 00:00:00 2001 From: Robert Milkowski Date: Tue, 28 Jan 2020 08:37:47 +0000 Subject: NFSv4: try lease recovery on NFS4ERR_EXPIRED Currently, if an nfs server returns NFS4ERR_EXPIRED to open(), we return EIO to applications without even trying to recover.
