No one complained about the release candidate,
so without further changes, this is the release.
> Changes since 8.4.7:
> * compat fixes for linux kernels up to 4.7
> * fix potential deadlock with many parallel request on kernels >= 4.3
> * fix potential data divergence after write error on secondary
> with non-synchronous replication
> * performance improvement for kernel >= 2.6.39
> use request plugging again to help backends with merging batches
> Already in 8.4.7-2:
> * compat: don't trigger BUG_ON on flush in kernel < 2.6.24 (e.g. RHEL 5)
> * al_write_transaction: skip re-scanning of bitmap page pointer array.
> Improves performance of random writes on "huge" volumes
> by burning less CPU and avoiding CPU cache pressure.
