I tend to run sparse over the nvme code before sending pull request
every time.  But it's a fairly new codebase, so it it actually
is clean.  I wish we'd just default to running sparse at some point
so people have to clean their shit up, as it catches a lot of
useful things.  But maybe for the default we want to tune it down
a bit (e.g. don't warn about missing statics by default, skip
the lock imbalance checks which while often useful also generate
tons of false positives).
