Subject: [PATCH 0/2] sunrpc: allow dprintk() to go to the trace buffer
 instead of console

While we have added a lot of static tracepoints in the last few years,
we still have a load of dprintks in place at all levels of the
NFS/NLM/RPC stack. At the same time, they're pretty useless under any
significant load.

This adds a new Kconfig switch to allow those to go to the trace buffer
instead. In addition to being more efficient, that allows us to enable
static tracepoints alongside dprintk() and get a unified log.
