By the commit for v5.1-rc1, ded52fbe7020 2019-02-20 nfs: fix xfstest generic/099 failed on nfsv3 NFSv3 stopped calling set_cached_acl(). And the behaviour changed. Is this intentional? Here is the example. (test script) f=fileA > $f getfacl --omit-header $f | tee $tmp setfacl -m u:$USER:rx,g:nogroup:x $f getfacl --omit-header $f | diff -u $tmp - || : setfacl -x u:$USER,g:nogroup $f getfacl --omit-header $f | diff -u $tmp - || : - on linux-v5.0, there is no difference between ext4 and nfs3. - on linux-v5.1-rc1, ext4 behaves same, but nfs3 doesn't show the "mask" entry in the last output. - removing user:$USER and group:nogroup entries looks "mask" entry gone too.
