| Subject: NFSv4: try lease recovery on NFS4ERR_EXPIRED |
| |
| From: Robert Milkowski <rmilkowski@gmail.com> |
| |
| commit 924491f2e476f7234d722b24171a4daff61bbe13 upstream. |
| |
| Currently, if an nfs server returns NFS4ERR_EXPIRED to open(), |
| we return EIO to applications without even trying to recover. |
| |
| Fixes: 272289a3df72 ("NFSv4: nfs4_do_handle_exception() handle revoke/expiry of a single stateid") |
