[PATCH 0/9] Overhaul btrfs-corrupt-block

[Nikolay Borisov <nborisov@suse.com>]

btrfs-corrupt-block is a very useful tool albeit very neglected. This series 
aims to give it much needed attention. There is a mix of code-improvements and 
bug fixes. Code improvement mainly consists of factoring our duplicated code 
(Patch 1,3,6) and improving the interface of some options (4,5,8,9). The
recurring topic here is that instead of having to pass 

btrfs-corrupt-block -K <key> -f <field> -<SOME OPTION WHICH CORRUPTS AN ITEM, 
POINTED TO BY K> 

make each corrupting option to take the key as an argument to it. Say we want
to corrupt an item field (-I options) we now do: 
 
 btrfs-corrupt-block -I <key> -r <root> /dev/blah 

 instead of 

 btrfs-corrupt-block -I -K <key> -r <root> /dev/blah 

Some patches also incorporate fixes for bugs (patch 2,7 and 9) I found during 
my testing. Those usability improvements are needed to enable me to produce 
tests for the pending free space tree support in userspace.
