Kent Overstreet 280481d06c 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.

config BCACHE
tristate "Block device as cache"
---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.

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

bool "Debug closures"
depends on BCACHE
select DEBUG_FS

interface to list them, which makes it possible to see asynchronous
operations that get stuck.
