Subject: [PATCH] NFSv4: open() should try lease recovery on NFS4ERR_EXPIRED
Date: Mon, 16 Dec 2019 17:54:22 -0000 [thread overview]
Message-ID: <05c201d5b439$d99083c0$8cb18b40$@gmail.com> (raw)
From: Robert Milkowski <rmilkowski@gmail.com>
Currently, if an nfs server returns NFS4ERR_EXPIRED to open,
we return EIO to applications without even trying to recover.
