Subject[PATCH 4.19 065/116] NFSv4: Fix v4.0/v4.1 SEEK_DATA return -ENOTSUPP when set NFS_V4_2 config
Date
From: Zhang Xiaoxu <zhangxiaoxu5@huawei.com>

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.

Fixes: bdcc2cd14e4e ("NFSv4.2: handle NFS-specific llseek errors")
