Should BLK_DEV_LOOP_MIN_COUNT be increased if this is enabled to
a mich higher sensible default? Right now the default is 8. Also,
can we infer this later dynamically so so this can grow at proper
scale without having to have user interaction?

For now, I mean something like:

diff --git a/drivers/block/Kconfig b/drivers/block/Kconfig
index 1bb8ec575352..22ba4803b075 100644
--- a/drivers/block/Kconfig
+++ b/drivers/block/Kconfig
