From d48d40a09127dfcb1f073c3e44de4b858393ae9e Mon Sep 17 00:00:00 2001 From: Vasily Khoruzhick Date: Mon, 14 May 2018 08:34:36 -0700 Subject: [PATCH] net: nfs: don't fail when nfs_read_reply returns -NFS_RPC_DROP That can happen if duplicate UDP packet arrived, and that's not uncommon. Anyway, we ignore packets with rpc_id lower than last we sent for other requests, so it makes sense to do that for read request as well.
