From: Zhao Lei <zhaolei@cn.fujitsu.com>

Hi, everyone,

These are v2 of cleanup patchs for raid56's scrub functions, it is
based on review for new-developed raid56's scrub code.

Some small typo-fix and cleanup for other functions are also included in
this patchset.

Changelog v1->v2:
1: scrib -> scrub in description.
   Suggested by: Brendan Hide <brendan@swiftspirit.co.za>
2: get/put_btrfs_bio() -> btrfs_get/put_bio()
   Suggested by: David Sterba <dsterba@suse.cz>
3: bbio->ref_count -> bbio->refs
   Suggested by: David Sterba <dsterba@suse.cz>
4: all ref_count -> refs in other code(new PATCH 16/16)
   Suggested by: David Sterba <dsterba@suse.cz>

Many thanks for above people for review these patch.

Thanks
Zhaolei
