Subject: [PATCH 0/4] dm verity: add support for error correction
Date: Thu,  5 Nov 2015 02:02:30 +0000	[thread overview]
Message-ID: <1446688954-29589-1-git-send-email-samitolvanen@google.com> (raw)

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
