[0/2] btrfs-corrupt-block btree data corruption

Message

Boris Burkov Feb. 4, 2021, 8:09 p.m. UTC

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.

  btrfs-progs: corrupt generic item data with btrfs-corrupt-block
  btrfs-progs: expand corrupt_file_extent in btrfs-corrupt-block
