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.

help
|
|
Don't select this option unless you're a developer
|
|
|
|
Enables extra debugging tools, allows expensive runtime checks to be
|
|
turned on.

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.
