| Subject: SUNRPC fix regression in umount of a secure mount |
| |
| From: Olga Kornievskaia <kolga@netapp.com> |
| |
| commit ec6017d9035986a36de064f48a63245930bfad6f upstream. |
| |
| If call_status returns ENOTCONN, we need to re-establish the connection |
| state after. Otherwise the client goes into an infinite loop of call_encode, |
| call_transmit, call_status (ENOTCONN), call_encode. |
| |
| Fixes: c8485e4d63 ("SUNRPC: Handle ECONNREFUSED correctly in xprt_transmit()") |
