+config BCACHE
+       tristate "Block device as cache"
+       depends on !PREEMPT_RT_FULL
+       ---help---
+       Allows a block device to be used as cache for other devices; uses
+       a btree for indexing and the layout is optimized for SSDs.
+
+       See Documentation/bcache.txt for details.

+config BCACHE_DEBUG
+       bool "Bcache debugging"
+       depends on BCACHE
+       ---help---
+       Don't select this option unless you're a developer
+
+       Enables extra debugging tools, allows expensive runtime checks to be
+       turned on.

+config BCACHE_CLOSURES_DEBUG
+       bool "Debug closures"
+       depends on BCACHE
+       select DEBUG_FS
+       ---help---
+       Keeps all active closures in a linked list and provides a debugfs
+       interface to list them, which makes it possible to see asynchronous
+       operations that get stuck.
