While I'm not eligible to say what should be done, my understading is
that Greg probably would prefer to have the "backport 06aa6eff7b"
version. What we know is that having now both commits in the
stable-rc/linux-5.10.y queue breaks  cifs and the backport variants
seens to work fine (Paulo Alcantara probably though can comment best).

As 06aa6eff7b smb3: Replace smb2pdu 1-element arrays with flex-arrays
was backportable to 5.10.y it should now work as well for the upper
one 5.15.y.
