From 5690eed941ab7e33c3c3d6b850100cabf740f075 Mon Sep 17 00:00:00 2001 From: Olga Kornievskaia Date: Thu, 24 Aug 2023 16:43:53 -0400 Subject: NFSv4.2: fix handling of COPY ERR_OFFLOAD_NO_REQ If the client sent a synchronous copy and the server replied with ERR_OFFLOAD_NO_REQ indicating that it wants an asynchronous copy instead, the client should retry with asynchronous copy.
