I have noticed a regression in lts test case with nfsv4 and this was 
overlooked in the previous cycle(5.15.154). So the regression is from 
153-->154 update. And I think that is due to nfs backports we had in 
5.15.154.

INFO: ltp-pan reported some tests FAIL
LTP Version: 20240129-167-gb592cdd0d


Steps used after installing latest ltp:

$ mkdir /tmpdir
$ yum install nfs-utils  -y
$ echo "/media *(rw,no_root_squash,sync)" >/etc/exports
$ systemctl start nfs-server.service
$ mount -o rw,nfsvers=3 127.0.0.1:/media /tmpdir
$ cd /opt/ltp
$ ./runltp -d /tmpdir -s fcntl17



This does not happen in 5.15.153 tag.

Adding nfs people to the CC list



Thanks,
