config BCACHE
tristate "Block device as cache"
select CRC64
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/admin-guide/bcache.rst 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.
