bcache: A block layer cache Does writethrough and writeback caching, handles unclean shutdown, and has a bunch of other nifty features motivated by real world usage. See the wiki at http://bcache.evilpiepirate.org for more. Signed-off-by: Kent Overstreet <koverstreet@google.com>

void bch_btree_verify(struct btree *);
bcache: Break up struct search With all the recent refactoring around struct btree op struct search has gotten rather large. But we can now easily break it up in a different way - we break out struct btree_insert_op which is for inserting data into the cache, and that's now what the copying gc code uses - struct search is now specific to request.c Signed-off-by: Kent Overstreet <kmo@daterainc.com>

void bch_data_verify(struct cached_dev *, struct bio *);
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.
