From 09e16905aca3c95c59ac77acf9851dd7d918ea56 Mon Sep 17 00:00:00 2001 From: Zhang Xiaoxu Date: Wed, 30 Jun 2021 21:04:19 +0800 Subject: [PATCH] NFSv4: Fix v4.0/v4.1 SEEK_DATA return -ENOTSUPP when set NFS_V4_2 config stable inclusion from linux-4.19.193 commit 1cfca6c32c2a6c41370010fcc4067e2d8dcfa02b -------------------------------- commit e67afa7ee4a59584d7253e45d7f63b9528819a13 upstream. Since commit bdcc2cd14e4e ("NFSv4.2: handle NFS-specific llseek errors"), nfs42_proc_llseek would return -EOPNOTSUPP rather than -ENOTSUPP when SEEK_DATA on NFSv4.0/v4.1. This will lead xfstests generic/285 not run on NFSv4.0/v4.1 when set the CONFIG_NFS_V4_2, rather than run failed.
