CIFS Unix Extensions - hardlinks (not symlinks) fail against master

In testing Sachin's DFS patch, I noticed an unrelated server bug -
cifs posix extension hardlinks seem broken against master

/mnt# ln -s file-in-test-target symlink-target ; ln
file-in-test-target hardlink-target
ln: failed to create hard link ‘hardlink-target’ =>
‘file-in-test-target’: Permission denied

Wireshark trace shows CIFS SetInfo Level 515 fails with access denied,
level 513 (with same kind of payload) works.
