Add a new stat that counts the number of times a remote TLB flush is
requested, regardless of whether it kicks vCPUs out of guest mode. This
allows us to look at how often flushes are initiated.

nit: this is a very x86-centric view of things. On arm64, TLB
invalidation is broadcast in HW, and does not interrupt the guest
execution.

We already have this queued for 5.15 [1].

I guess you mean the change for "remote_tlb_flush" has been queued,
not "remote_tlb_flush_requests"?
These two counters would have the same value for arm64, but not for
others (at least x86).

Yes, this is what I meant, as I only quoted the bit that was redundant.

Sure. It is just that this patch does two things at once, but doesn't
advertise it.

All in all, Jing's new stat is more appropriate than the one I used.
I'll fix the conflict when pulling from you.
