There is a rebase error at:

  247560698349 ("Merge tag 'v5.10.30' into v5.10-rt")

Cherry-pick mainline's commit:

  bc8e0adff343 ("net: xfrm: Use sequence counter with associated spinlock")

and your compilation issue will be fixed.

Good luck,

Thanks for this fix, Cherry-pick resolved rt stable integration issue 
that i was seeing.

Is this fix going to be posted for v5.10-rt too ?

Yes, I'm pulling it in now (sorry for the delay).

For some reason, Yann's email never made it into my INBOX :-/

But cherry picking that commit appears to do the job. I'll pull that in,
and then start bringing 5.10 to the latest release.
