Here are two patches which I cooked up while working on the kernel side of backup
root retention code. The first one fixes '-m <bytenr> -f generation' options to 
btrfs-corrupt-block, allowing me to simulate backup root corruption. 

The second patch is a test case which sanity checks the implementation. It suceeds
both before and after my rework of the kernel code.

  btrfs-progs: corrupt-block: Refactor tree block corruption code
  btrfs-progs: tests: Test backup root retention logic
