tristate "Block device as cache"
bcache: use routines from lib/crc64.c for CRC64 calculation Now we have crc64 calculation in lib/crc64.c, it is unnecessary for bcache to use its own version. This patch changes bcache code to use crc64 routines in lib/crc64.c.

bcache: prefer 'help' in Kconfig Current bcache Kconfig uses '---help---' as header of help information, for now 'help' is prefered. This patch fixes this style by replacing '---help---' by 'help' in bcache Kconfig file.

Allows a block device to be used as cache for other devices; uses
a btree for indexing and the layout is optimized for SSDs.
docs: Fix some broken references As we move stuff around, some doc references are broken. Fix some of them via this script: ./scripts/documentation-file-ref-check --fix Manually checked if the produced result is valid, removing a few false-positives.

bcache: Debug code improvements Couple changes: * Consolidate bch_check_keys() and bch_check_key_order(), and move the checks that only check_key_order() could do to bch_btree_iter_next(). * Get rid of CONFIG_BCACHE_EDEBUG - now, all that code is compiled in when CONFIG_BCACHE_DEBUG is enabled, and there's now a sysfs file to flip on the EDEBUG checks at runtime. * Dropped an old not terribly useful check in rw_unlock(), and refactored/improved a some of the other debug code.

turned on.

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.
