Subject: [PATCH] NFSv4: Fix v4.0/v4.1 SEEK_DATA return -ENOTSUPP when set
NFS_V4_2 config
Git-commit: e67afa7ee4a59584d7253e45d7f63b9528819a13
Patch-mainline: v5.13-rc4
References: git-fixes
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.
