I noticed that RXE is disabled in RHEL9.x. And in RHEL 8.x, RXE still
is enabled.
It seems that RXE is disabled in RHEL 9.x because of instability.
And recently RXE accepted several patch series.
IMO, we should have more time to make tests and fix bugs before the
new patch series are accepted.

This can make RXE more stable. And more linux distributions will enable it.
Or else, more and more linux distributions will disable RXE. Less and
less users will use RXE.
Finally RXE will never be used in the future.

I think, this is not what the RXE guys expect.

As such, it had better have more time to make tests and let RXE more stable.
We should not accept too many patch series in short time. Too many
patch series will bring risks.
