I'm trying to enable the use of KCSAN on NFSD. There are some false
positives that make the signal-to-noise ratio unfavorable.
The noisiest data races we (NFSD chickens) have direct control over
are the per-RPC and per-pool statistics. These two patches try to
address those.
There might be some additional desirable changes. For example, we
could make the RPC counters per-net. I'm saving up those pennies
for another rainy day.
