Subject: [PATCH 0/2] dm vdo: additional metadata validation
Date: Wed, 11 Feb 2026 10:05:53 -0500 [thread overview]
Message-ID: <cover.1770818146.git.msakai@redhat.com> (raw)
We identified a few places where dm-vdo uses a value from
storage without sanity-checking that its value makes sense.
Adding additional checks can prevent additional metadata
corruption in the unusual cases where these values get
corrupted.

dm vdo indexer: validate saved zone count
dm vdo slab-depot: validate old zone count on load
