This patch set adds error correction support to dm-verity, which
makes it possible to recover from data corruption in exchange of
increased space overhead.

The feature is implemented as part of dm-verity to take advantage
of the existing hash tree to improve performance and locate known
erasures.

Sami Tolvanen (4):
  dm verity: clean up duplicate hashing code
  dm verity: separate function for parsing opt args
  dm verity: add support for forward error correction
  dm verity: ignore zero blocks
