Register read/write tracing is causing excessive
logging and filling the rtb buffer and effecting
performance.

Doesn't this series depend on the MMIO tracing series? Why not just
make it part of that one?

As stated before, I do not think this is a copyrightable change, and
will be glad to discuss that with your corporate lawyers if they insist.

It is already a part of MMIO tracing series - https://lore.kernel.org/lkml/cover.1651663123.git.quic_saipraka@quicinc.com/
There was some disconnect before but they have been informed. Now this series will be dropped and
will be taken as part of MMIO tracing series.
Thanks,
