| Subject: PNFS fallback to MDS if no deviceid found |
| |
| From: Olga Kornievskaia <kolga@netapp.com> |
| |
| commit b1029c9bc078a6f1515f55dd993b507dcc7e3440 upstream. |
| |
| If we fail to find a good deviceid while trying to pnfs instead of |
| propogating an error back fallback to doing IO to the MDS. Currently, |
| code with fals the IO with EINVAL. |
