Subject: [PATCH v2 0/2] btrfs-corrupt-block: btree data corruption
Date: Fri, 15 Jul 2022 14:22:10 -0700	[thread overview]
Message-ID: <cover.1657919808.git.boris@bur.io> (raw)

Add some more generic corruption to btrfs-corrupt-block which allows
corrupting the data in metadata items.

Motivated by testing fsverity which requires rather specific corruption
of the metadata.

The first patch adds corrupting arbitrary regions of item data with -I.
The second patch adds corrupting holes and prealloc in extent data.
