This series tries to reduce the amount we hold the ilock exclusively,
especially during direct I/O writes where they currently hurt us.

Dave showed that his earlier version which is less aggressive than this
one can already provide magnitudes of better throughput and iops for
parallel direct I/O workloads, and this one should be even better.
