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 @@ -217,7 +217,8 @@ config BLK_DEV_LOOP config BLK_DEV_LOOP_MIN_COUNT int "Number of loop devices to pre-create at init time" depends on BLK_DEV_LOOP - default 8 + default 8 if !ZONEFS FILESYSTEM + default 32 if ZONEFS FILESYSTEM help Static number of loop devices to be unconditionally pre-created at init time.
