From 431794e67e238e6fd170499a14fd2abf0a16b5bd Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 18 May 2022 17:08:58 -0400 Subject: pNFS/files: Handle RDMA connection errors correctly The RPC/RDMA driver will return -EPROTO and -ENODEV as connection errors under certain circumstances. Make sure that we handle them correctly and avoid cycling forever in a LAYOUTGET/LAYOUTRETURN loop.
