Subject: [PATCH v2] NFSv4: try lease recovery on NFS4ERR_EXPIRED
Date: Wed, 8 Jan 2020 21:48:29 -0000 [thread overview]
Message-ID: <115c01d5c66d$5dcd7ae0$196870a0$@gmail.com> (raw)
From: Robert Milkowski <rmilkowski@gmail.com>
Currently, if an nfs server returns NFS4ERR_EXPIRED to open(), etc.
we return EIO to applications without even trying to recover.
Fixes: 272289a3df72 ("NFSv4: nfs4_do_handle_exception() handle revoke/expiry
of a single stateid")
